Description

hi all,

tvheadend crashes while recording multiple channels. It also occurs while recording and watching, but it's easier to reproduce with just recording.

small config description:
- DN2800MT + 8GB memory
- PLEXTOR PX-128M5S as storage (and a bigger disk, but that's left out of this test)
- Digital Devices GmbH Mystique SaTiX-S2 V3 DVB adapter dual tuner (DVB-S2)
- Hauppauge Nova-TD dual tuner usb stick (DVB-T)

For this tvheadend setup I configured one dvb-s2 tuner and 1 dvb-t tuner. I also configured the cardserver specifics of course (and AFAIK it's not directly related to the cwc's).

I configured the muxes and services and some other stuff (can upload the config if needed) and I can record and watch tv.

One of the stress tests I always try to do is running as much recordings and watching as much channels as possible (for the moment the cardserver and the amount of tuners are the limit).
When I start recording on multiple channels (both dvb-s2 and dvb-t) it runs well for a while, but then it crashes. I had this issue for a while but didn't have the time yet to run it in a debugger.

I attach the debug log file and the gdb logging output. If necessary I can upload the tvheadend binary and the coredump as well, but the coredump is around 750MB in size).

kind regards

Jouk

last message before crash: psi: tables count inconsistency (num 37, list 36)
that's a message I've seen a few times.
I got (almost) rid of them by disabling "over the air EPG" at the adapter level. I grab EPG with a timer at a quiet moment.

#2

Updated by Jouk Hettema - about 10 years ago

will certainly try that. Got another crash this morning (test rig). As far as I could find it isn't on the dvb-t tuner but only on the dvb-s2 tuner. Will try to narrow it down to see if it has to do with a certain channel/mux.

will also try with and withou over the air EPG.

I am sorry to say that I got these crashes as well. I thought the memory corruption problem/bug was gone (see my case no 2296, https://tvheadend.org/issues/2328) but I recently got two crashes with the same line in the beginning of the crash report:

It seems that they are related to timer recordings. I did not have a crash for 7 days and as soon as I had one or more recordings starting the crashes also started.

hi,

I don't think it's just related to DVR. I just found out that while my wife was watching (via XBMC) a channel tvheadend crashed again. When I looked at the logging there was no recording scheduled.

Below the logging from that moment in time:

Because I have monit running for this specific situation there was only a 15 second gap between the crash and the moment she could continue watching. For now that'll work, but I think it needs to be fixed because AFAIK it's a rather fundamental part where it goes wrong (gut feeling...).

If I need to setup a test environment for collecting coredumps (or upload the coredumps I already have) and other information, please let me know.

kind regards

The bad thing is that it is really difficult to debug this. Do you use any other EPG source ? Timeshift ? Other tvh features ?

#8

Updated by Crazy Fin about 10 years ago

I understand the difficulty of debugging this... :-(

I use ONLY "EIT:DVB Grabber" under the tab "Configuration" -> "Channel/EPG" -> "EPG Grabber". No other EPG Grabbers at all.

I have even disabled "Over-The-Air EPG" for each of my 8 tuners under "Configuration" -> "DVB Inputs" -> "TV adapters".

Under "Configuration" -> "DVB Inputs" -> "Networks" I have "Network Discovery" and "Idle Scan unchecked" and "Skip Initial Scan" checked.

Under "Configuration" -> "DVB Inputs" -> "Muxes" I have set all my enabled Muxes to "Only EIT" on "EPG Scan"

Under "Configuration" -> "Channel/EPG" -> "EPG Grabber" I have set "Force initial EPG scan at startup:" to disabled and the Cron multi-line has the default setting:

"_# Default config (02:04 and 14:04 everyday)
4 2 * * *
4 14 * * *_"

"EPG scan timeout in seconds (30-7200):" is set to 900

"Periodic save EPG to disk" is set to 4 and the 3 tick boxes about updating channel name, number and icon is set to ticked.

Updated by Crazy Fin about 10 years ago

Forgot to mention that I have Time Shift disabled.

#10

Updated by Crazy Fin about 10 years ago

As I mentioned above I have DISABLED all EPG modules except the EIT: DVB Grabber. That is the ONLY tick box I have enabled.

However, I can see in the startup log that TVH still creates all EPG modules:

Updated by Lee Pru about 10 years ago

Just wanted to say that I'm also getting this only in last update today. I updated from version 3.9.383 to 3.9.1588 and tvheadend does not stay up for more than 30-60 minutes. The syslog is showing:

I have a good experience with valgrind to detect the wrong memory accesses, so if you can trigger this bug in this short time and you're on fast machine, you may try to run the tvh under valgrind (compliled from source using all debug symbols). I'm using this cmd line:

valgrind --leak-check=full --show-reachable=yes ./build.linux/tvheadend <your tvh options>
#13

Updated by Mark Clarkstone about 10 years ago

  • Priority changed from Normal to High

- Changing this to high as it affects more than a few people.

Been running tvh in valgrind with a single tuner for a good 17+ hours now while running another script (perexg gave me) that switches channels and it has yet to crash! :s

On my second machine, I've set all 7 tuners to use and it appears to be working fine here too.
I've only ever experienced this crash when using xbmc.

It's a strange one!

Updated by Jouk Hettema - about 10 years ago

hi all,

got a crash this morning with the 1600 version of tvheadend. It didn't generate a core file and I just have the log message.

When I tried to setup a valgrind/debug configuration I found out there were quite some continuity errors on the interface. If possible I will replace the LNB tomorrow which is the most likely cause of these errors. When that's done I'll try to setup a cleaner solution to test tvheadend in valgrind.

regards

Jouk

ps: it's a strange one indeed. But, I have the feeling it only happens on DVB-S2 interfaces. Would it be helpfull if we describe the different setups in some detail?

#15

Updated by Jaroslav Kysela about 10 years ago

The commit c72cadbd5da151b748f58bd4eb9f6de1d111489a might make a difference.. But the whole coverity fixes can play a role to fix this bug.

#16

Updated by Jouk Hettema - about 10 years ago

didn't replace my lnb, but giving the newest version on git a go. Just compiled it and now it's recording 4 channels which gave me the most psi crashes.

#17

Updated by Jouk Hettema - about 10 years ago

afraid it isn't fixed :( got the error after 30 minutes of recording.

#19

Updated by Mark Clarkstone about 10 years ago

I'm still running tvheadend from within valgrind trying to get it to crash, but it just wont!

Seeing as you guys have the crash more frequent than I do, do you think you could run valgrind with your setup and post the results when it crashes?

Mine crashed again last night after running for about 24 hours, so I set it up through valgrind again, but it could be a while before it finally does bork out!

#20

Updated by Jouk Hettema - about 10 years ago

my server is to small in cpu resources for running tvheadend in valgrind. I can start it and it runs, but it's hardly useable.

As I haven't seen this error in a couple of days I would like to lower the priority if that's ok with you guys?

#21

Updated by Crazy Fin about 10 years ago

Please do not lower the priority. I got a crash like this one (psi: tables count inconsistency (num 24, list 15)) last night after 18 hours of running latest build 3.9.1743.

During the coming weekend I will try to setup to run TVH in Valgrind. Would be great to "nail" this memory bug, except for this bug, TVH is now running really nice (at least for me. :-) )

#22

Updated by Mark Clarkstone about 10 years ago

I'd just like to add, I'm been running build 3.9.1738 now for just over 20 hours without any errors so far. Newer builds (1741 in this case) keep crashing for me not sure if related to this bug.. gdb log here. http://sprunge.us/aUME

#23

Updated by Jaroslav Kysela about 10 years ago

I added in v3.9-1901-g43e805d the table number / list inconsitency check to more subroutines. I hope that we can do different crashes with this patch to locate the bug . Please, compile with --enable-trace (as always) and provide crash reports..

#24

Updated by Crazy Fin about 10 years ago

Ok great since I am still getting these errors until the version 3.9.1889.

To compile with --enable-trace:

Do I enable the trace functionality with "./configure --enable-trace" before I do the actual compilation with "make -j5"?

#25

Updated by Crazy Fin about 10 years ago

Sorry I also forgot to ask that when I start TVH with

"./build.linux/tvheadend -l tvh.log"

should I still start it with the debug and trace parameters as well?

Like
"./build.linux/tvheadend -l tvh.log --debug all --trace all" or what debug settings should I start TVH with?

It's sufficient to configure the tvh build with --enable-trace otherwise the extra checks are not included to the code. It's not required to enable trace at runtime.

#27

Updated by Crazy Fin about 10 years ago

OK thanks so I´ll do

./configure --enable-trace

and then start TVH with

./build.linux/tvheadend -l tvh.log --debug all

or is even sufficient with

./build.linux/tvheadend -l tvh.log

I had a crash again last night (running 3.9-1901) and I will collect the gdb coredump tonight when I´m back at home. 9 out of 10 times these crashes has happened during midnight and approx 6 am in the morning.

#28

Updated by Jaroslav Kysela about 10 years ago

Note I fixed another issues (which looks very promising regarding this bug). Please, upgrade to v3.9-1911-ge1d8c2a .

#29

Updated by Crazy Fin about 10 years ago

Ok great! I have now pulled in v3.9-1911-ge1d8c2a and I am running it now with

./build.linux/tvheadend -l tvh.log --debug all

as well as core dump enabled as per https://tvheadend.org/projects/tvheadend/wiki/Debugging

Let's keep fingers crossed that you have been able to fix this annoying bug. :-)

Will report back tomorrow morning.

#30

Updated by Crazy Fin about 10 years ago

Sorry but still crashing... :-(

Again at midnight. This is so strange since TVH is running during the day pretty nice. 99% of the crashes I get happens between midnight and 6 am.

tvh.log (cut down the log to few minutes before crash) and core dump (gdb.txt) attached.

#31

Updated by Jaroslav Kysela about 10 years ago

Could you enable 'mpegts' trace to get more debug logs ? --trace mpegts

#32

Updated by Crazy Fin about 10 years ago

Sure, will do that tonight when back at home from work.

./build.linux/tvheadend -l tvh.log --debug all --trace mpegts

or is

./build.linux/tvheadend -l tvh.log --trace mpegts

enough?

Funny you should mention that this is what was happening to me as well, always in the morning.

#34

Updated by Crazy Fin about 10 years ago

Strange, now when I have been testing TVH to catch the crashes I have started TVH with either

./build.linux/tvheadend -l tvh.log --debug all --trace mpegts
./build.linux/tvheadend -l tvh.log --debug all
or just
./build.linux/tvheadend -l tvh.log

and now I get a crash everytime I stop TVH from running with CTRL-C.

I guess this is not a problem to bother about at this stage.

I am now running latest TVH build 3.9.1926~g917fb80 --trace mpegts enabled. Lets see if we can get usable crash data tonight.

#35

Updated by Crazy Fin about 10 years ago

Alright got another crash after 2 hours of running this morning.

Final part of tvh.log attached (let me know if you need the full log file) and gdb.txt attached.

Hope this gives you some idea on where the memory corruption happens.

Let me know if you need further debugging.

#36

Updated by Crazy Fin about 10 years ago

2 hours more and another crash.

New tvh.crash.log and gdb.txt attached.

#37

Updated by Jaroslav Kysela about 10 years ago

Thanks. I added some more mpegts traces to the source. I know that this debugging is annoying, but if you can trigger this bug, it will help to others..

Also, please, provide the more complete log (if possible) - the grep for :mpegts: lines (say last 10 minutes) and complete last lines from log (like now) might be sufficient. Thanks.

#38

Updated by Crazy Fin about 10 years ago

I am on 3.9.1950.

Got a crash now after almost 2 days without any crashes. This crash looks different from the previous crashes though.

Alright, got a crash this morning again with your new tracing functionality. I hope you can see something else now that will help you nail this memory corruption bug. :-)

Attached is the last hour of the tvh.log and the gdb.txt output.

Let me know if you need any more logging. It seems to me that these crashes happens at least 1 or 2 times per day.

#49

Updated by Crazy Fin about 10 years ago

This obsveration is quite interesting!

I have had the "Idle Scan" turned off for 2 days now and NOT a crash yet...

#50

Updated by Jouk Hettema - about 10 years ago

That's the case with me as well.

Haven't seen a crash in days/weeks, so my wife and kids are happy campers. However, afaik I have never enabled the idle scan feature on my cards.

Soon I'll have a third sat tuner in my system so I can do some more testing.

Interesting, I have "Idle Scan Muxes" enabled on all networks and no crashes recently (currently running 1992).

I'm currently using the following:-

PCTV Nanostick 290e single tuner DVB-T2 (USB)
Hauppauge Nova-TD dual tuner DVB-T (USB)
Tevii S471 single tuner DVB-S2 (Pcie)
Tmax TAS2101 (A.K.A TBS 5922) single tuner DVB-S2 (USB)

Running kernel 3.10.38 with lja's linuxtv media tree from github.

I was previously using the above with a Hauppauge stick (same chipset as the TD), an RTL DVB stick (you know those Chinese cheapies with FM/DAB) all DVB-T and a Technisat Skystar DVB-S2 USB HD, when I experienced the crashes, I may connect these back up at some point and see if I get any crashes again.

Seems really weird how you're getting crashes frequently and I'm not anymore..

#52

Updated by Crazy Fin about 10 years ago

Sorry but crashed now after 3 days of running without idle scan enabled.

This time the crash message is a little bit different:

"double free or corruption (top)" but still in the same module "src/input/mpegts/mpegts_input.c"

Should I create this crash as a new bug ticket or shall we keep on adding into this ticket?

gdb.txt is attached as well as the last 30 minutes of tvh.log.

OK, I think that I found the wrong code.

https://tvheadend.org/projects/tvheadend/repository/revisions/7f1d851a404a84cbe266923cfeecb92995291b8b/diff/

Please, upgrade to v3.9-2081-g7f1d851 and let me know the result.

Again, the recent crash messages has been somewhat different but still related to the same part of the source code? I am not sure if I need to create a new bug ticket for this error:
