Bug #3466
Out of Memory -> KILLED
0%
Description
Just as an adhoc info, it happend during a recording & live view:
[ 5780.489863] Out of memory: Kill process 913 (tvh:lnxdvb-fron) score 960 or sacrifice child
[ 5780.489930] Killed process 913 (tvh:lnxdvb-fron) total-vm:5666264kB, anon-rss:3593032kB, file-rss
:0kB
My tvh-server has 4 GB and this never happend.
Sorry for no-debug. I will install the debug version tomorrow, today I'm back to 1264 because I need to reccord for my wife (WAF-important :-))

With HTS Tvheadend 4.1-1284~ga5085c8 I couldn't reproduce the crash so far but what I've seen is that in time shift mode old data is not deleted. I've configured 1 GB as Ram-Buffer and even with a time shift of some seconds this seems to be filled over the time (screenshoot) and then the next buffers are written on the disc.
I will cancel my ram buffer to not running into short of memory situations anymore.
Maybe you can close this ticket.
btw. the advantage of the memory buffer is smaler now, because the disc is needed anyway after some time.

I'm back to 1264 - this is the last "stable" version for me.
1284 also as 1286 hangs without a usable message after few seconds :-(

Updated by 4.1-1258~gb480c92 is the last stable version in my case, using IPTV only. In all subsequent releases after zapping a while the tvh process gets unresponsive. Not even using timeshift nor recording. Using Kodi Jarvis B4 as a client.

This is pretty much the same for me but DVB-S/S2/T/T2, I will continue to test git master.

Is this definitely fixed? I was testing a recording last night after I had enabled a new profile and timeshifting. Before finishing the recording the process was killed as all memory had been used (including swap).
It appears as if the buffer wasn't being written to the HDD and freed properly, meaning it kept growing until it was killed.
My build is:

Sorry to reopen it again, getting this error too while recording.
I have ~5-10 recordings at one time and measured my disc write speed with
dd if=/dev/zero of=/home/waldmeister/test123 bs=1G count=1 oflag=direct 110 - 140 MB/s
How can i provide more tests?
Updated by C K about 8 years ago
So i really don't think thats HDD speed related. There must be another problem. Maybe timeshift?

Create a new issue. Provide screenshot of 'Config / Debugging / Memory information entries' when tvh eats too much memory.
