Bug #6002
Endless increase in RAM requirements
0%
Description
Same problem like https://tvheadend.org/issues/5648 on my QNAP TVS-882 since using FW 4.5.x.
I am using TVH 4.3-1919~g52b255940 with the QPKG from virtualdj.
I see that suddenly my used RAM increased very fast up to 100% limit of 48 GB (later even up to 64 GB). After some more tests, I see that after restarting TVH, the RAM is free again and the normal state is reached. Later I see that TVH consumes up to 20 GB of RAM and more in this critical state. This stops when I restart TVH. I got the tip from virtualdj to stop the OTA EPG and the problem stopped occurring. After a few days I restarted the OTA EPG and the problem occurs again. Running up to 7 recordings the same time is not a problem. I saw in the log during this critical state the following message repeated endlessly.

What is result of this?
I run TVH on 2Gb system without problems.
Updated by Harald K over 3 years ago
Just now this gives no result. But now the problem don't exist, I don't run the OTA-EPG now.
I have to add the information: I run this constellation since about 4 years without problem. Only since the update from the QNAP-fw the problem occures. I'm not sure that the reason is only TVH. Sometime everything runes for days without promlems. Bus for example last week I started the OTA-EPG end the problem occures direct in this moment.
I made a lot of tests. Fist I thought that my virtualization system is the problem, I run some virtual machines on this QNAP. I opendes a ticket with QNAP without result. I changed my RAM. But then I see that everytime I run in this problem it is solved by restart TVH.
Another point: My QNAP has now 64 GB RAM. In the moment that TVH usage of memory increases to high values like 10 GB and more the QNAP shows me a usage of nearly 100% of the 64 GB. I'm not a specialist, so I absolutly don't understand this.

There have been several memory leaks fixed in the latest version. Some in the opentv-grabber which could be the cause for this.
The logs indicate some kind of lock, so you might want to check with gdb to see why it's stalled and not processing any more input data.

I could not compile the latest versions for Harald K to try. The last version that builds correctly is bbf76ca, then with c5d4d7d and onwards I always get this error:

Harald K, maybe you should post the zipped trace log, as running gdb on the QNAP (an embedded system) is not feasible.
Updated by Flole Systems over 3 years ago
That compile issue will be fixed soon.
Why is running gdb on an embedded system not feasible? There is no point on posting logs, you need to figure out the cause of it. The logs are just showing the consequences, you need to find the cause. Maybe you can try to use the deadlock detector in Tvheadend (see the Wiki for details about that) but other than that there is not much which can be done without using gdb.
Updated by Harald K over 3 years ago
I must try to reproduce the problem with running debug. Then I'll post the trace log. Unfortunately I'm a stupid user, things like gdb are very strange for me.
Updated by Flole Systems over 3 years ago
Again: A trace log does not help. It will only show the consequences and not the cause. No need to waste time with that.

OK, sorry, didn't know about that.

Probably I've overstated, anyway to have TVHeadend run on the QNAP (which uses ancient glibc 2.21) I compile it on a Debian VM and then move all the required libraries (including the Linux dynamic loader ld.so) to the QNAP.
For gdb it's the same: it is not included and must be compiled from sources. Or maybe, if we're lucky, the version shipped with Entware might work, but I've never tried before.
Updated by Flole Systems over 3 years ago
Sounds like you're talking about a common architecture like x86 or i386, so use your preferred search engine and find a statically compiled version of gdb and you can just run it. As you only need it a few times (and have plenty of diskspace available) that is probably the easiest solution. But be aware: You need Tvheadend with debug symbols, so that's something you need to keep in mind while compiling.
Updated by Flole Systems over 3 years ago
The fix for the compile issue is in now, so you should be able to compile again.
Updated by virtual dj over 3 years ago

Yeah, confirmed working, thanks!
But be aware: You need Tvheadend with debug symbols, so that's something you need to keep in mind while compiling.
Just to be sure, is it the --enable-ccdebug option, right? The wiki doesn't mention when compiling from sources, just to use the "-dbg" packages...
Bear in mind that I'm using --enable-bundle to have a single TVHeadend binary, are the debug symbols included inside the binary itself?
@Harald K
You can download the compiled binary (4.3-1936~g0046c96d8) from here:
https://www.dropbox.com/s/0b1oaucnfkh65xb/tvheadend.zip?dl=1
Extract the file and overwrite the one you have in /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/
(replace CACHEDEV1_DATA
with the one correct for your NAS).
Updated by Flole Systems over 3 years ago
What you compiled contains the debug symbols, so it's all good.
If you look at the Wiki you can also try to use the thrdebug-Flag when starting Tvheadend. But gdb is much more promising. If you write a coredump it will write all memory used by Tvheadend to a file and you can also later on restore that state with gdb and pull more information from it if needed.

@virtual dj: I have done an now 4.3-1936~g0046c96d is running on my QNAP.
Thank you all very much.

I've tried on my NAS, to be sure that I'm doing the things right. I'm writing the complete procedure here, so Harald may reproduce it if/when he will have the thread lock.
- I've installed gdb from Entware (available at Qnapclub.eu) with:
[/share/Public] # opkg update [/share/Public] # opkg install gdb [/share/Public] # gdb -v | head -n 1 GNU gdb (GDB) 10.1
- I've copied the
libthread_db.so.1
from my VM into/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/
(where the dynamic loader libs reside) to avoid the following error:warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.
You can download it from here: https://www.dropbox.com/s/6vfadtmiyi2gk6o/libthread_db.so.zip?dl=1 - I've created a
.gdbinit
file like so:[/share/Public] # echo "set auto-load safe-path /" > /root/.gdbinit
... to avoid the error:warning: File "/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/libthread_db.so.1" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
- With TVHeadend running, I run gdb like so:
[/share/Public] # gdb tv $(pidof tvh-loader) ... cut ... [New LWP 20009] [Thread debugging using libthread_db enabled] Using host libthread_db library "/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/--Type <RET> for more, q to quit, c to continue without paging-- libthread_db.so.1". 0x00007effefe4035b in pthread_cond_timedwait@@GLIBC_2.3.2 () from /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/libpthread.so.0
At first sight it seems correct, but what doesn't convince me is that if I type:
(gdb) bt #0 0x00007effefe4035b in pthread_cond_timedwait@@GLIBC_2.3.2 () from /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/libpthread.so.0 #1 0x00007efff0b1798f in ?? () #2 0x00007ffc15d26c60 in ??

()I get all those question marks, just as the symbols are not loaded correctly. Sorry, I'm not a developer and I'm still trying to learn. Is this output correct? So do the missing symbols come from the libc that I ship with TVHeadend binary to have it run on the NAS?
Because if I type:

TVHeadend/bin/libc
folder that is where I copied the required libraries, while bin/libc/tvh-loader
is the ld.so
that I renamed. It's not tvheadend
that runs directly, but tvh-loader
(the dynamic loader, hence that pidof
command) that launches tvheadend
.
I also tried a different gdb, a static version that you suggested, such as this:
https://github.com/hugsy/gdb-static/blob/master/gdb-7.10.1-x64
but it's even worse and it still has the ??.
Updated by Flole Systems over 3 years ago
I am not entirely sure I fully understand what you are doing there, but you need to attach directly to Tvheadend. I have no clue what that magic loader is doing and how it works, but your result should be a proper stacktrace and not just question marks. Also is your tvheadend binary really called tv? Otherwise the gdb command to attach isn't correct.
Updated by Harald K over 3 years ago
Hmmm, I'm not really sure what I have to/can do now. Now 4.3-1936~g0046c96d8 is running some days without any problem, but also without ota-epg. I thought next step can be to try to activate ota-epg with debug trace all? Of cause I'll wait to do this for a less critial time, when there are no recordings planned and no other things running and I have the time to take care for the NAS.

You should activate ota-epg, but as Flole Systems said, you should NOT trace but instead, when you see the RAM increasing and the [WARNING]:mpegts: too much queued table input data (over 2MB) message on the log, attach gdb to it and create a core dump file.

Mmm, I suspected that.

I cannot run tvheadend directly on the NAS: if I do, it won't run because it has an ancient libc. So I run:
[/the/copied/libc/folder] # ./ld.so --library-path /the/copied/libc/folder /my/application/path/tvheadend --forkto circumvent this problem. Maybe the pid that I attach to is the one of ld.so, so that probably causes the "??" symbols? The problem is I don't see any other pid with ps, other than ld.so.

No, but if I run (I renamed the file to stick with the example):
[~] # gdb /my/application/path/tvheadend $(pidof ld.so) ... cut ... [New LWP 19956] [New LWP 19957] [New LWP 19958] warning: Build ID mismatch between current exec-file /my/application/path/tvheadend and automatically determined exec-file /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader exec-file-mismatch handling is currently "ask" Load new symbol table from "/the/copied/libc/folder/ld.so"? (y or n)In either case, i.e. I reply "y" or "n", I still get the "??" in the stack trace.

Basically:
- tvheadend binary (that one that I've compiled above) resides in
/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/tvheadend
- the ld.so has been renamed (to avoid clashes) as
/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader

Ok, seems I have to do this. Please be patient, I'm very stupid in this topic. "attach gdb to it and create core dump file" means first to study what that will say to me.
Exactly at the moment I started manual the ota-epg (22:49) the memory used by TVH increases from about 200 MB to about 2.2 GB, after the end of ota-epg it falls to about 1.9 GB. Parallel running recordings seems to have no real influence on the memory, but while the running of the automtic ota-epg (02:04) I get some messages for about 5 minutes like this (but no increasing use of memory)

It looks like you are receiving only Astra 19.2E, right? I can receive that one aswell, I'll see if I can somehow reproduce this behaviour.
Before using GDB it's necessary to figure out why it's not working properly and only outputting questionmarks. I think this might be related to the way it is executed. @virtual dj might be able to check if it works properly on the host that built this binary. I am not sure about this but it might be possible to simply replace the path to the ld.so in the binary file (as long as the new name has the same length!!!) and that should get around this issue.

Okay, new situation: now there started a recording some minutes ago, no ota-epg is running but the message
2021-02-23 13:37:25.128 mpegts: too much queued table input data (over 2MB) for Sundtek DVB-S/S2 (VIII) #0 : DVB-S #0, discarding new

seems to come endless, TVH don't react, memory usage increases.
So I'll stop the ota-epg and wait for news.

I can assure you this is driving me nuts! Sorry for the long post, but I would like to prove that I'm not just sitting on my hands ;-)

You're right, of course it is . I've tried to reproduce the issue with this simple file:
root@debian-x64:~# cat pid.c #include <stdio.h> #include <unistd.h> #include <stdlib.h> #include <sys/types.h> int main() { pid_t pid; /* get the process id */ if ((pid = getpid()) > 0) { printf("The process id is %d\n", pid); } printf("Type 'q' to exit.\n"); char exit; do{ exit = getchar(); }while(exit != 'q'); return(0); } root@debian-x64:~# gcc -O2 -g -o mypid pid.c
I've moved this
mypid
file to the QNAP and if I run it normally, i.e. with the QNAP supplied ancient libc, and then attach gdb to the process, I can see the symbols:[/share/Public/gdb] # ./mypid The process id is 7344 Type 'q' to exit. ^Z [3]+ Stopped(SIGTSTP) ./mypid [/share/Public/gdb] # gdb ./mypid 7344 GNU gdb (GDB) 10.1 ... cut ...

You can see it's looking to the /lib/ path, with the old libc (that the simple program can use, but TVHeadend of course cannot).
Then I've tried to run the small program under the Linux loader (just as TVHeadend):
[/share/Public/gdb] # /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader --library-path /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc ./mypid The process id is 12766 Type 'q' to exit. ^Z [1]+ Stopped(SIGTSTP) /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader --library-path /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc ./mypid [/share/Public/gdb] # gdb ./mypid 12766 GNU gdb (GDB) 10.1 ... cut ...

() #4 0x0000000000000000 in ?? () (gdb)
You can see that it cannot load the symbols from the source anymore... the same if I reply 'n' to the exec-file-mismatch error in gdb (of course, because it sees the loader running, not the mypid application):
... cut ... warning: loading /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader Not confirmed. Reading symbols from /lib64/ld-linux-x86-64.so.2...

() #7 0x0000000000000000 in ?? ()
So the problem that I'm trying to solve is how to tell gdb to load the symbols correctly. I've tried what you suggested with the sample program, i.e. using patchelf to add the loader and rpath (which is longer as you can see) but it results in an "Illegal instruction".
The only way that I was able to do it is compiling the source like so:
root@debian-x64:~# gcc -O2 -g -o mypid2 -Wl,-rpath /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc -Wl,--dynamic-linker=/share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader pid.c
Which sets a fixed loader path in the new
mypid2
and then if I try to debug this new executable, it works of course:[/share/Public/gdb] # ./mypid2 The process id is 23844 Type 'q' to exit. ^Z [1]+ Stopped(SIGTSTP) ./mypid2 [/share/Public/gdb] # gdb ./mypid2 23844 GNU gdb (GDB) 10.1 .. cut ... Reading symbols from ./mypid2... Attaching to program: /share/CACHEDEV1_DATA/Public/gdb/mypid2, process 23844 Reading symbols from /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/libc.so.6...

Now it loads the correct libc and it displays the correct symbols. Unfortunately I still don't know how to apply that to the TVHeadend binary compiled above, which of course needs a lot of libraries to be run correctly.
I also tried the method described here to attach the symbols afterwards:
https://sourceware.org/glibc/wiki/Debugging/Loader_Debugging#Debugging_With_an_Alternate_Loader
but I was unable to... probably I'm doing something wrong. I used the add-symbol-file command but in my opinion the address that I must specify as argument is not correct (according to the linked article) and still results either in ?? or in wrong symbols.
I won't give up, but I need some fresh ideas... believe me that this is very new (and hard) for me to understand only by Googling and trial & error.
P.S.: Another idea that I thought is to edit the TVHeadend sources to trigger a crash (just like --abort) when the error mpegts: too much queued table input data (over 2MB) is printed and then launch TVHeadend on the QNAP using the --dump switch. Might it produce anything useful, in this way?
Thanks for your patience.
Updated by Flole Systems over 3 years ago
I think I've already mentioned the solution: Use a hex editor and edit the path to the ld.so The new path has to be the same length, so you might have to give it a weird name but other than that it should work.
You don't necessarily need to trigger a crash, attaching should usually show you something inside Tvheadend as a stack trace.

I just ran an epg scan and used valgrind to watch out for memory leaks and I didn't see any extreme RAM usage and valgrind also didn't catch anything. Unfortunately a NAS is one of the worst platforms to run valgrind, so that is most likely not an option for you.
Just to rule out a driver issue: Can you please try to disable the Sundtek device and use only SAT>IP and see if that changes anything? Also another idea might be to use the Lock-debug feature, but don't expect too much from it: https://tvheadend.org/projects/tvheadend/wiki/Debugging#Mutex-profiling
Once it's slow to react you should see long mutex long times being shown.
It looks a little like you were running the epg grabber while a recording was running and then the issues started appearing? Maybe that is what triggers in on your machine?
Updated by Harald K over 3 years ago
I had running this configuration for years without any problem wit one single tuner direct at the QNAP (sundtek) and another one as sat->ip on a raspberry pi. I always run only the ota-epg. Some months ago (October or November) QNAP roll out a new firmware. Exactly at this time ma single sundtek was killed. So I changed it to the currend 2xdual tuner. All in all the same range time I changed the tuner, firmware and some other Apps on the QNAP (especially upgrading the virtualization station) but not TVH. Since then I have tis problem. Only same weeks later I upgraded TVH, without any effect since now. I also changed the RAM without effect.
I don't know what is the reason of all, but I see that the problem always occures togeteher with TVH. If I restart TVH everything is ok. But not all RAM is used by TVH. My VM uses about 16 GB, QTS less the 1 GB, some others also some GB and all in all about 24 GB and not more of 64 GB. But if the problem starts and TVH uses 10-20 GB the system complete uses 64 GB. I knoew about the cache and such things, that's not the problem.
This issue appers independent of recordings. I can run more then 5 recordings same time without problem.
Updated by Harald K over 3 years ago
Now I run TVH with only the SAT-IP-tuner activated and runnung ota-epg. And also now the usage of RAM of TVH increases up to about 1 GB in this time and stays there. Second start with the same conditions yields nothing strange.

OK, I succeeded it eventually, I had to edit the interpreter as you said (no luck with gdb's add-symbol-file).
@Harald K
Remember that this will change your TVHeadend directory to allow debugging, so when we'll finish you'd better remove this stuff and rollback by reinstalling the original QPKG. That's another story.
- Install Entware QPKG from the Qnapclub.eu repository to have gdb (I tried with a static build but it complains for libthread_db, while Entware's doesn't).
- Download this file and copy it into
/share/Public
: - Stop TVHeadend and expand the contents on a new folder (remember that gdb will write core files, which are very big, here):
[/share/Public] # tvheadend status TVHeadend status: STOPPED. [/share/Public] # tar zxf package.tar.gz -C ./package/ [/share/Public] # cd package [/share/Public/package] #
- Install gdb using Entware:
[/share/Public/package] # opkg update [/share/Public/package] # opkg install nano patch gdb [/share/Public/package] # echo "set auto-load safe-path /" > ~/.gdbinit [/share/Public/package] # echo "set pagination off" >> ~/.gdbinit
- Copy the required files to the TVHeadend installation directory, and patch the script (pay a lot of attention to the correct PATH if it's different from yours):
[/share/Public/package] # cp ./tvheadend /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/ [/share/Public/package] # cp ./libthread_db.so.1 /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/libc/ [/share/Public/package] # patch /share/CACHEDEV1_DATA/.qpkg/TVHeadend/TVHeadend.sh ./script.patch patching file /share/CACHEDEV1_DATA/.qpkg/TVHeadend/TVHeadend.sh
- Start TVHeadend, check that there are no issues (I've tried in my system and it runs):
[/share/Public/package] # tvheadend start ... cut ... TVHeadend started.
- Now, as a first test, try to attach gdb to the running TVHeadend:
[/share/Public/package] # ./gdb /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/tvheadend $(pidof tvheadend) Reading symbols from /share/CACHEDEV1_DATA/.qpkg/TVHeadend/bin/tvheadend...

The question marks finally disappeared! :-) - If this is working like me, detach the debugger by quitting (q and then y):

- Let TVHeadend run and wait until the problem arises. When it does, attach gdb again like on the previous point (pay attention to be in the
/share/Public/package
folder because the files will be created here) and then issue this commands:(gdb) set logging on Copying output to gdb.txt. Copying debug output to gdb.txt. (gdb) thread apply all bt full ... cut ...

- The gdb.txt file and the core.10238 file (the latter is huge) are those Flole System needs (please correct me if I'm wrong). Zipped, of course.
Updated by Flole Systems over 3 years ago
Please don't upload or send me the core file, it contains a snapshot of the entire Tvheadend memory (including the credentials of the users if they were in memory). In addition to that it's useless without the binary and the ability to execute it, so I couldn't even look at it. Once you have a core file you can do the debugging and see what was going on at that point. It's really not difficult, but let's wait for the issue to appear again
Updated by Harald K over 3 years ago
Now I reached step 8, but step 7 yields not the right thing. It seems something is not correct installed up to here.

When it appears, capture the log and core file but as Flole has written, take them apart without uploading and wait for his instructions.

I think it's correct, you should do the same that you did previously. The scope of gdb is to inspect what component causes the lock.
Updated by Harald K over 3 years ago
You are right, my failure. In the second echo I use the ">" instead of ">>".
The reason of my "stupid question". Since I use the two dual tuner my intension was to use only the 5th tuner (sat->ip) for the ota-epg, otherwise it is very boring and only very seldom is used. So last days I do so because the idea of Flole and then the use of RAM is high, about 1 GB, but don't increase up to now. I thought it can be a reason that all tuners do the same while ota-epg.
But of cause, you are right, I have to run now the same situation like before to find the real reason. I hope I have a look on my system in the right moment - some time I have to earn some money....

Yes, I think it's due to the different loader (used to allow debug with gdb, as written above) that interfere with XMLTV, because I have the messages in the log:

When TVHeadend spawns those scripts with --description
probably they fail (due to the different libc) and so they don't return any data and are thus excluded from the candidates.
Until you're using this "debug version" of TVHeadend you won't have access to the XMLTV automatically.
However, in the mean time, you can invoke your grabber manually (from SSH) and post the data to TVHeadend.
Enable the External: XMLTV grabber module in TVHeadend and look at the sock file; you can use it like this (adapth path and XMLTV grabber):
# opkg install socat # tv_grab_?? --days 7 | socat - UNIX-CONNECT:/share/CACHEDEV1_DATA/.qpkg/TVHeadend/config/epggrab/xmltv.sock
Updated by Harald K over 3 years ago
Yes, it's the same here: No XMLTV grappers listed in EPG Grabber modules. I'll try the External XMLTV. But now the main point of view is the ota-epg.
Is it right, I start the gdb only when the problem occures. Is it not to late?
This moment everything runs fine, no problem with ota-epg, recording and nothing. Strange to hope now the problem occures soon.

No, it is not. If I've understood well, when you see the [WARNING]:mpegts: too much queued table input data... message on the TVHeadend log it means it is (actually one of its thread I believe) locked into something and it doesn't have "time" to process the input data (= too much queue).
So when you see these message, you attach with gdb and create a log file of the current stack (with thread apply all bt full
) and a core file (with generate-core-file
). These two files are a snapshot of the state of TVHeadend, including its memory.
Then it should be possible to load this core file in gdb and inspect where the program is "stuck" (the stack should reveal the order of the operations that led to that situation). I don't know how to do this, but Flole Systems will certainly help.

Now I have the files gdb.txt and core.18346 (which is about 15 GB) - what to do now?
Something is different against the time before: The total used RAM of the QNAP didn't increase up to the limit this time.
Updated by Flole Systems over 3 years ago
You can publish the gdb.txt file, that shouldn't contain any personal data. Make a search for your username and password in it though to be on the safe side.
Just to confirm: The Webinterface was completely unresponsive and Tvheadend was completely locked up?
Updated by Harald K over 3 years ago
TVHeadend increases the used RAM between about 23:15 04:05 last night. Unfortunately this time I'm not at the computer so I'm not sure wether the Webinterface s resonsive or not. When I have a look on it this morning everything seems to be all right only TVHeadend uses about 12 GB RAM

TVH uses about 15 GB, the QNAP all in all uses up to 62 GB. I have started all my VMs with about 40 GB to force this situation. But if I add all RAM used by the main applications this value is not 100 % RAM.
Here I add again the gdb.txt.
I stopped most of the VMs now, but TVH don't react anymore. It seems I have to restart it now for continue working.

Now you can go through the steps described here. Your Thread IDs will obviously be different, so you need to see where they are coming from (usually from the previous line) and what your IDs are.

Check this... It could help you, about how to use gdb.
As you have a coredump you can use gdb to load that coredump (with the -c parameter instead of specifying the PID) and then you can pull the information from Tvheadend while it was locked up.
Updated by Harald K over 3 years ago
Excuse me, I have to add: It seems that free RAM by stopping the VMs helped at the moment: Nor I have access to TVH without restart it. Two running recordings this time seem to be continued with only some failures (one recording 13 failures and the other 14 failures).
Okay , so I'll try to go through the core file. Give me some time - I repead: I'm very stupid in this topic. Thank you very much for your patience. I'll write here if I get some information - ore questions.

What version on what system? Looks like it's not a NAS, so you can most likely do better debugging and even use valgrind to see if there is indeed a memory leak.

That sounds like Tvheadend is simply out of memory and becomes unresponsive because of that. In that case there's no real point in continuing with the gdb analysis, it is necessary to figure out why the memory usage is so high.

I've tried to reproduce loading a core file in gdb (even though I don't have your issue so all is going well in my case) and I get the ??? in the stack trace, too .
So probably it's better to attach gdb during the issue, without relying into the core file? I mean, when you have the error, invoking gdb as we did before (using the PID) and then typing print global_lock
and so on...

Updated by Harald K over 3 years ago
I got the problem back very quickly. This time the RAM requirement increases almost immediately when restarting TVH and then OTA EPG within 6 hours continuously to about 20 GB, of course again with the above warning. Unfortunately the complete issue is now so long that I could not copy everything from the terminal. I hope the most important is included. My QNAP now also needs the complete 64 GB RAM. I need again to restart TVH

Hi, please don't consider this message as a push, just an information request. I know that there are a lot of things to do and you're following this project in your spare time, so no problem here!
But I'm just becoming curious: do you think that with the log above (post 57) you can understand a little more about the cause of the OP issue? I see that there are no missing symbols this time.
Of course I'm not able to interpret this kind of log :-(
Updated by Harald K over 3 years ago
I have to give also some new information: Some days ago (02. March 2021) QNAP offers an update of its fw and I installed it 2 days 16 hours ago. Since then the RAM usage of TVH seems not to be to high. Of cause, this can be an random.
Updated by Harald K over 3 years ago
Some news:
After a few days with a RAM requirement of approx. max. 130 MB, the RAM requirement jumped 10-fold to approx. 1.4 GB within an hour during a recording yesterday. This recording also ran for exactly one hour. The last few days this did not occur with other recordings After that it remained constant again for hours, even during the OTA EPG.
Updated by Harald K over 3 years ago
The issue comes again and again. now it seems more often after the start of recordings. So my next action is to change this debugging-version to the last version and use without ota-epg but external-xmltv.

Sorry but I'm not skilled in C enough to decode the stack trace above myself, otherwise I would have tried...
Updated by Harald K over 3 years ago
Doesn't matter. I'm happy about every try and you have done much effort.
I had done one step in between: Continue using the debugging-version but stop the ota-epg and try to use the external xmltv like you wrote in #37. If I get back my old single tuner repaired from sundtek I'll try the container-solution. But I'm waiting since now for it for some months. But that's another topic. Another idea was to get the epg from my raspberry pi with its TVH and save this like written in #37 to the QNAP. But first I have to be sure the ota-epg is really the problem.
Up to now the only solution seems to be to have always a look on the system and restart TVH the right time. Not very comfortable and not so save, of cause.
Updated by Harald K over 3 years ago
I'm not happy: Now this issue commes without activated ota-epg. I'll restart TVH again now.

Based on the log it looks like Tvheadend got stuck during the unsubscribe. That would need further investigation now with gdb to see what the thread which should be joined is doing now. I don't think thats the reason for the memory increase though.
Updated by Harald K over 3 years ago
Sorry, but I don't know what this all means. It seems this problem occures only on my system and only since the last main step of the firmware of the QNAP. On the other side it touchs mainly TVH and can be stopped by restarting this. Unfortunately I'm the absolute idiot on this topic and don't absotutly understand what all the loggings will tell me.

I've tried to reproduce loading a core file in gdb (even though I don't have your issue so all is going well in my case) and I get the ??? in the stack trace, too .
Definitely I'm stupid or was thinking to something else... I've found the reason why the core dump file didn't load with the symbols in gdb! It was the command line that was missing the TVHeadend binary!
Harald K, do you still have the original core files? Otherwise I'll recap here the correct way to create them.- Start TVHeadend
[/share/Public/package] # tvheadend start [/share/Public/package] # tvheadend status TVHeadend status: RUNNING.
- Wait for the issue, when you see the mpegts: too much queued table input data messages on the log, attach gdb to TVHeadend:

Now TVHeadend is still running (because gdb has been detached) and you can either stop it or let it run, it doesn't matter when you have the core file.
But here was the error! The core file is called, in this example, core.11058; scrolling up in the ticket, I saw that you (and I of course) used this command line:
[/share/Public/package] # gdb --core=core.11058 ... cut ... Core was generated by `/share/CACHEDEV7_DATA/.qpkg/TVHeadend/bin/tvheadend'. #0 0x00007f9e6a6ce35b in ?? () [Current thread is 1 (LWP 11058)] (gdb) bt #0 0x00007f9e6a6ce35b in ?? () #1 0x0000000000000000 in ?? () (gdb) q
But this is wrong! We must specify the path of the executable, too, so this is the correct way:

You can see that we're operating correctly on the core file, and this work also with TVHeadend stopped (provided that there is the same binary on the path we used to capture the core file):
[/share/Public/package] # tvheadend stop [/share/Public/package] # tvheadend status TVHeadend status: STOPPED.

However, when TVHeadend is stopped, the /tmp/tvh-loader is removed (you can see the warning) so it's better to keep it running or re-create the symlink manually before running gdb:
[/share/Public/package] # /bin/ln -sf /share/CACHEDEV7_DATA/.qpkg/TVHeadend/bin/libc/tvh-loader /tmp/tvh-loaderHope this helps troubleshooting faster, as you don't have to wake up at night to attach gdb again!

Now that I think we've solved the issue with the core file, can you provide some instructions to do what you've asked with gdb?
Updated by Flole Systems over 3 years ago
Select thread 1 again and figure out which thread de->de_thread points to. Then select that one and see what that thread is doing (bt full). There should be a dvr_thread if I remember correctly but that doesn't seem to be there in your gdb.
Updated by Harald K over 3 years ago
Since my last restart of the QNAP and so also restart TVH thy system runs without problems (without using ota epg). Unfortunately this time I'm not so free in my time so pleas let me some time watching wether theproblem occurs again. But I can do the do the steps that virtual dj has written because I have the first core file saved - only I'm not sure wether the issue was the right one that time.
Updated by Harald K over 3 years ago
I see one main differency of my output against that one of virtual dj. But I don't find something like "de->de_thread"
virtual dj:
(gdb) print global_lock

the difference is
__size = "\002\000\000\000\000\000\000\000\252G\000\000\003", '\000' <repeats 26 times>, __align = 2

Yesterday I have the issue again while ota-epg don't run. But the problem seems to be not so bad this time, because the system continues running and TVH works without failures. What do I see? The warning: "mpegts: too much queued table input data (over 2MB) for Sundtek DVB-S/S2 (VIII) #2 : DVB-S #0, discarding new" in the log, unfortunately it vanishes later and I can't exactly say what time this happens. You know, my system has 64 GB RAM, so it seems this time the problem was "not big enough"??
12:25 the usage of RAM starts to invrease until 15:25 from 9,5 GB to 5.2 GB. This time 2 recordings are running: one 12:25 until 13:40, the second one 12:49 until 14:04, both on the same channel.
15:25 the increasing stops until 15:50, then it continues until 16:35 to about 6 GB. Since then there is no change, but 2 more recordings in the evening have no influence.
But last view days I see that this issue often happnes (if it happens) at this time when start recording this channel. Random?
Of cause I startet gdb with the steps above. But there is nothing to see. Here are the last steps:

The error (too much queue...) simply means there's something wrong and it's generated here:
https://github.com/tvheadend/tvheadend/blob/736ac427b1934832aab23391f5ce35f687c999c6/src/input/mpegts/mpegts_input.c#L1548
So probably it could be possible to put a breakpoint there and stop TVHeadend in that moment and then capturing the core file. You'll lose the recordings, though (because the breakpoint stops/pauses TVHeadend itself).
(gdb) break mpegts_input.c:1548
Just for my curiosity:
(gdb) print dvr_rec_unsubscribe::de->de_thread $2 = 139859662386944 (gdb) thread 2why did you switch to thread 2? I do not think "$2" means "thread 2" but I would search for "139859662386944" which is the variable value (don't know where, actually...
thread find 139859662386944
maybe?).Updated by Harald K over 3 years ago
Then I really misunderstood. I thought $2 meant thread 2.
For my understanding: You mean I have to wait for this warning, start exactly in this moment gdb with THV and the current pid and then direct without all the other steps type
(gdb) break mpegts_input.c:1548
Updated by Flole Systems over 3 years ago
You printed a pointer, so that's an address in memory which you have printed there. You should do something like
print *dvr_rec_unsubscribe::de->de_thread
to retrieve the data at that address.
There's no point in breaking at the warning, all you'll see is that the buffer is full, which we already know. To me it starts to sound like a problem with the recordings if that's when the RAM usage increases, have you tried a different caching method?
Updated by Harald K over 3 years ago
What do you mean by "different caching method"?
The issue not only occuers while recordings and not while all recordings. Somtime it occures direct after starting TVH somtimes not for several days.
And again: This runs for more than 4 years on this machine without problems. Only since the last update of the fw of the QNAP.

Yes, but also the TVHeadend version has been updated, so you cannot be sure that the culprit is only within the QNAP firmware. If it was possible, you should have run the same version of TVHeadend with the old firmware, but you can't.
Flole Systems wrote:

Sorry, my fault!
So Harald try to reopen the core file and see what:
print *dvr_rec_unsubscribe::de->de_threadprints.
Updated by Harald K over 3 years ago
The result is
(gdb) print *dvr_rec_unsubscribe::de->de_thread
$2 = -1652640000
(gdb)
I think this fact is not really important to find the failure. But You are right, I had updated two times TVH since the (main) update of the fw of the QNAP. But the failure with the RAB occures first time before this updates of TVH when I'm running the same version of TVH since long time. Only I don't see this time that it occures in combination from QNAP-fw and TVH.
I have to say sorry to you both, Flole Systems and virtual dj. It must be hard to work this style with someone like me: Completely stupid in this topic and need always mach time for the answer ...

How do we search that -1652640000 value on the threads list?
(gdb) thread find -1652640000doesn't seem good, with a negative value, isn't it?
Updated by Harald K over 3 years ago
I have one more idea: The fact that not only ota epg but also recording is the source of the failure is not true. Perhaps my configuration is not correct for this. I have stopped the cron for the ota epg but I don't disable the ota epg grabber. So when a recording starts the ota epg for this channel also starts.
Now I'll really disable the ota epg. I'm not so happy about this, because the xmltv is not so precise like the opta epg. Some channels are completely not included.
Updated by Harald K over 3 years ago
Since my last post here and running really without OTA-EPG and 2-3 restarts of TVH (because other reasons) the problem don't occure.
virtual dj: I'm running an older version of TVH on the raspberry pi and use it as sat->ip sever for this TVH on the QNAP. Is it possible to use the OTA of the EPG as an external XMLTV-base?

I don't know if there's a way to "export" the OTA EPG from TVHeadend as a XMLTV file (to use it to feed the xmltv.sock in the other TVHeadend instance running on the QNAP). Probably not?

Sorry for the stupid question from a total layman: Is anything happening regarding this bug?
Updated by Jonathan S over 3 years ago
I run tvheadend on a Liva X x86-64 mini PC with Debian Buster and have a similar issue. Just a few minutes ago, tvheadend was using all 2GB of my RAM so I tried saen acro's suggestion https://tvheadend.org/issues/6002#note-1 :
sync && echo 3 > /proc/sys/vm/drop_caches
This recovered the memory but shortly thereafter a recording started and all RAM was was immediately consumed by tvheadend. I tried the above command again while the recording was ongoing, but this time there was no change in memory usage. So at least in my case it looks like the memory leak is associated with recording and not with the EPG.
Updated by Flole Systems over 3 years ago
Most likely you aren't seeing a memory leak but a simple "can't write to HDD fast enough". Data is then cached in RAM. That shouldn't be related to this issue though (and is NOT an issue but perfectly normal behaviour), as in this case the issue is not there when EPG grabbing is not happening, recordings don't seem to matter.
Updated by Jonathan S over 3 years ago
Flole Systems Systems, write speed benchmark with a recoding in progress is 135 MB/s. I think that is plenty fast enough to keep up with a recording.

Then your caching settings might be wrong. Feel free to investigate the memory leak though if you really think there is one, I don't think so though.

Have you got some suggestions on how to proceed and detect the EPG possible "issue" using the core file?
I mean, you didn't reply to my post number 83.
You said:
Select thread 1 again and figure out which thread de->de_thread points to.
And we got:
(gdb) print *dvr_rec_unsubscribe::de->de_thread $2 = -1652640000 (gdb)
Then select that one and see what that thread is doing (bt full). There should be a dvr_thread if I remember correctly but that doesn't seem to be there in your gdb.
So now, how do we select the thread identified by -1652640000 and see what it is doing?

@Harald K
As we cannot get out with this gdb situation, after reading other tickets more carefully (such as #5579, #5353, #5295 and #4851), I found that we (you) didn't try to enable what Jaroslav suggested:
https://tvheadend.org/issues/5579#note-5
So please edit the TVHeadend start script /share/CACHEDEV7_DATA/.qpkg/TVHeadend/TVHeadend.sh
, search for the word administrators
(there should be 2 lines, apply to both of them) and edit from this (original):
--user admin --group administrators \to this (modified):
--user admin --group administrators --thrdebug 10020 \Then run the script in debug mode, so it will write the log into a file in
/share/Public
(it applies the --logfile
TVHeadend argument, so it should write stderr contents too, hoperfully):# tvheadend debug startAccording to the wiki, after you get the problem again, in the log text in /share/Public you should see something like:
thread: mutex 0x5562f9f859e0 at src/api/api_idnode.c:134 took 43ms thread: mutex 0x5562f9f859e0 at src/api/api_idnode.c:134 took 31msand a file mutex-deadlock.txt should be created into

Yep, of course. So edit TVHeadend.sh again, search for the line:
# Interactive mode: output to stderr too CMDLINE_OPTS="${CMDLINE_OPTS} --stderr"and change it by replacing stderr with fork, in this way:
# Interactive mode: output to stderr too CMDLINE_OPTS="${CMDLINE_OPTS} --fork"(so both the two if parts do the same). This way you will still have the log in /share/Public (I'll fix this in a future version).

https://github.com/tvheadend/tvheadend/blob/1619f9e44678dba5467e4ac94b3e47ea92b72f3e/src/tvh_thread.c#L491
In fact:
https://github.com/tvheadend/tvheadend/blob/1619f9e44678dba5467e4ac94b3e47ea92b72f3e/src/tvh_thread.c#L447
So the file should be there, I suppose...

Now I startet TVH once again with debugging after I restart the NAS completely yesterday.
But again TVH crashes very soon with the message:
/usr/bin/tvheadend: line 746: 29315 Aborted /usr/bin/env ${TVH_CMDLINE_PREFIX} LD_LIBRARY_PATH=${QPKG_DIR}/bin/libc:${QPKG_DIR}/bin/libc/no-codexpack ${QPKG_DIR}/bin/tvheadend --config ${QPKG_DIR}/config --user admin --group administrators --thrdebug 10020 ${CMDLINE_OPTS} ${TVH_CMDLINE_POSTFIX}
I add the logfile in the appendix. Starting TVH withoud debugging works fine. Very fist time after the last post from virtual dj also works fine with debugging.

This does not help, as it doesn't show anything about why it crashed. It's very strange that it crash only when debugging.
Post 96 instead was more useful and showed a deadlock at least exist. Why it exists is another matter, unfortunately.

You are absolutely right: Unfortunately.
Last days I searched for alternatives to the ota epg. But its not really successful. There are some ways like XMLTV, WebGrab+Plus and easyepg. The last one is not so bad and free for use. But it's not the same range like ota epg and it's very complicate for installation. I run the first part - the real grabbing - on a linux VM on the NAS and only the second part - connect to the TVH-socet - on the NAS.
Unfortunate that such a great project apparently can not be maintained. But I have this problem now nearly since half a year.

Please excuse my (parhaps stupid) question:
Will something happen here at some point?
