Public bug reported:
Binary package hint: mythtv
When recording from a "Satelco EasyWatch DVB-C MK3" DVB-C card I see a memory
leak in mythtv-backend.
The system seems to allocate about 0.2% of the 4Gb ram installed in the backend
every minute until the memory usage rises to about 80% then the system starts
swapping and becomes totally unusable.
When the recording is finished the memory is not released. The only way to
release the memory is to stop/start the mythtv-backend process.
kernel 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64
GNU/Linux.
My cable provider sends DVB-C in QAM256.
The problem could be related to EIT and the option "Close DVB card when
not it use".
mythbackend version: 0.21.20080304-1
I've run the backend under valgrind and have attached the log file.
Valgrind started with the following options:-
valgrind --leak-check=full --error-limit=no --show-reachable=yes
--log-file=logfile -v -- /usr/bin/mythbackend
--daemon --logfile /var/log/mythtv/mythbackend.log --pidfile
/var/run/mythtv/mythbackend.pid --noupnp | tee backend.log
