Bug #3305
Memory leak
0%
Description
With issue #3294 I've udpated to version 4.1-971~g5192186. Since then tvheadend is running out of meemory after a few recordings are started at the same time.
I've updated now to 4.1-988~g82776a4, but the memory issue is still there. I tried to get a coredump, but am unsuccessfull to get one trying with guide https://tvheadend.org/projects/tvheadend/wiki/Debugging.
Syslog:

Updated by I'm not sure if it's related to DVR. I tested several configuration and cannot reproduce the leak here. Could you try to isolate the behaviour to a restricted config?
Updated by Anonymous about 9 years ago
I'm getting more and more issues last week. Let me recreate the config, then I will report back. This will be probably in a few days.
Updated by Anonymous about 9 years ago
I've reinstalled tvheadend and recreated my config. The result is the same, tvheadend is running out of memory after a few recordings are started.
I've reverted now back to the prod version 4.0.7 and recreated the config again. The system is now running stable for almost 24 hours. Memory consumption of the tvheadend process is less then 1% of total memory.
Environment:
As OS I'm running Ubuntu 5.10. Hardware is Intel NUC D54250WYK with 4GB RAM and 60GB SSD. As a tuner I have HDHomerun HDHR3-4DC. My system is using latest oscam-svn for decoding my Ziggo Smart Card.
I'm recording directly on a samba share connected with 1GB to my Synology DS412+.
In the config I created 22 autorec entries. And as postprocessing command I'm running comskip (issue remains when disabling this).
Because it's my production system, and I need to keep my family happy, I needed to go back to a stable environment again. If you like to investigate this further, please let me know this and I can try to setup a similar test environment trying to reproduce the issue.

Updated by Just a small addition, I have also memory problems since version 4.0.8, however it will not crash tvheadend, but the system gets very slow (due to the high memory) and when playing or recording a lot of continuity errors occur. After a reboot the system will work flawless for a couple of hours without any continuity error.
I already tried a fresh install, was running Ubuntu 14.10 and now on Debian 8, but both with the same result, the logging is clean.
Since I don't watch TV very often I can use this server for debugging purposes, but at this moment I have no idea where to start.
