[mythtv-users] oom-killer?

[Udo van den Heuvel]

Hello,

When I leave the MythTV box running over nights I see that the
oom-killer becomes active for various processes. From small applets to
the mythbackend.
The box has 512MB (minus 64MB for video).

Swap:            0          0          0

So what is wrong here?
Any ideas?
