MKV playback leads to oom-killer
Issue #137
resolved
With firmware 20140305 and a 3.6 GB MKV file (1 hour and 50 minutes), 1916x798, 23.976 fps, h.264 High@L4.0, AAC 2 channels @ 48kHz, 160kbps One video track, one audio track, one subtitle track without language code, 17 additional subtitle tracks with various language codes, 16 chapters defined.
At around 30 minutes into playback, the "busy spinner" appeared on the screen while playback continued for about 15 seconds, then playback stuttered and stopped for about 5 more seconds and then enigma2 just restarted. No crash dialog and not a reboot, just a restart of enigma2. Same crashing experience at around 65 minutes, then again at around 72 minutes and from there about every 5 minutes until the end of the movie!
When reproducing the issue, I managed to capture this via serial console:
matroskademux0: invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0
