Hi
I run a pretty heavily utilised freevo 1.52 box for recording free to air tv via an analog tv capture card and mencoder. I have begun to notice rather alarming memory usage patterns with the freevo record server threads which make me think either something is leaking memory or not using garbage collection where it should. Not being overly familiar with Python memory management I don't dare to guess what exactly is going on, but consider the attached memory usage stats taken from top output.
Over a period of 4 days and about 18 recording events, the resident memory consumption of the record server seems to have gone from 42Mb to 165Mb while the main process and the web server have remained roughly constant. It doesn't looks like there are any orphaned mencoder child processes hanging around or anything unusual. If I leave the recordserver for long enough, eventually enough memory is taken up that most other processes are swapped out of physical memory and mecoder begins to thrash because of insufficient buffer space during recordings. Right now I restart the recordserver manually every few days but it is hardly an optimal solution.
Anybody have any ideas or suggestions about what to do? This is freevo 1.52 (Gentoo ebuild) running on Python 2.3.4 over a 2.4.26-gentoo-r14 tree kernel with V4L and MPlayer 1.0pre5try2-3.3.4.
Thanks in advance.
