Description
I have a memory leak on my mythtv. It started when I switched from an old fashion tv (analog) card to a DVB-C card. The amount of memory growth changes between idle and recording. If I am recording the leek is about 5-10x higher then in idle. (In Idle mode mythtv is scanning my channels for EIT data. I do not use any XML grabber as our broadcaster offers 7 Days of EPG on a transport stream.)
I tried to produce vallgrind logs, however I can not keep valgrind running for a long time as it kills the rest of my system: 99% CPU usage during recording -> frameloss and mythweb not working properly.
I hope all needed information is included. If you need any additional info let me know. The problem happens in the 21.fixes branch to. I just switched to trunk in the hope it would be less segnificant there.

Mythfrontend was not running during valgrind test.
I am currently restarting mythbackend with a cron job twice a week to guarantee proper operating. If I keep it open longer it is killed due to extensive memory allocation.

I had this same thing happen on my machine (Core 2 Duo x86_64). Was watching live TV, everything was fine for a while, but after a scheduled recording completed, a subsequent recording did not occur. At this point, I lost keyboard/remote control, and noticed my memory usage was skyrocketing. I have 4G of RAM. System at idle, watching live TV, mythfrontend normally uses approximately 5.4% of RAM, but at the time this was going on, usage was at 51% and climbing rapidly. I had to kill the frontend and bounce the backend to get things to recover.
comment:4 Changed 11 years ago by
Sorry, one other detail. My CPU usage for mythfrontend went from it's usual 14% to 38%

Same valgrind log we keep seeing for this issue.

hmm, this is definitely a PES packet we're keeping too long. Since you say this goes up when you are not collecting EIT it must be a PAT/PMT or NIT/SDT table.

I built a fresh svn checkout of mythtv-fixes on 11 october 2008. I installed it on the 12th of october. Some early figures:

Just 1 Terratec Cinergy 1200 DVB-T card with 7 virtual tuners of which 3 are more or less 24/7 recording 3 TV channels off of one multiplex. Back to back programs overlap 2 minutes max (1 minute at begin, 1 minute at the end). The machine has 1GB of RAM and is running on a VIA Epia EN12000.

Full Valgrind Log of 5min Recording
comment:12 Changed 11 years ago by
I have currently a spare Core2Duo machine. I made a test setup for mythtv with valgrind. The System is setup using mythubuntu 8.10 with latest weekly build of mythtv.

I still have the usual memory growth of about 100MB per Hour. I did a 1hour recording and a 5minute recording, both with valgrind running. As it is a test setup without any personal data on the machine I offer to put the machine into a dedicated subnet accessible from the internet and pass the login to a developer if it helps to figure out the source for the memory growth.

Please run valgrind with t5545.diff applied. It should at least make the leak smaller.
I suspect that we might read a PID with video data as PSIP. That's at least the only way I can explain PES packets larger than 65536 bytes.

Your patch did not produce any additional output on my system. So I also addad an else statement to doublecheck if the debug output was working. Result:

t5545_fix1.diff hopefully fixes the issue
The DVB tables have all empty destructors but since the data gets copied in the constructor they all would leak memory. Since we keep track of all the tables except of the NIT other the leak is rather small if no NIT others are transmitted.

(In [19705]) implement DVBStreamData::DeleteCachedTable? to properly delete cached NITs and SDTs
it needs to be implemented in ScanStreamData? too due to multiple inheritance Fixes #5545

I experience similar (but not so extreme) growths of memory. I us e Terratec Cinergy 1200 DVB-T card with multirec to record three SD TV channels 24/7. Recently I started using EIT for soem radio channels besides the XMLTV based TV channels.
My stats so far: # cat /home/udo/psmyth.txt |cut -b16-65 %CPU %MEM VSZ RSS TTY STAT START TIME
I had a small crash of the backend at the empty line. I can not reliably run valgrind on the VIA EN12000 board: mythbackend gives strange errors and does not run well.
