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.
I am running Gentoo as well, and my amd64 system started going into swap
space w/ a gig of memory due to freevo recordings using mencoder. I posted a
message to this list about it and the workaround I found. No-one replied to
that thread, but you can find the message and the workaround here:

My Freevo box is an IA-32 system, so your initial hypothesis about a 64
bit safeness thing can be discounted. I will use your workaround and
have a closer look at the record server code for the allocation you
described. Thanks a bunch for the reply.
