During the last week, I've had several
crashes on my backend.
$ /usr/local/bin/mythbackend --version
Please include all output in bug reports.
MythTV Version : 16332
MythTV Branch : trunk
Library API : 0.21.20080224-1
Network Protocol : 40
Options compiled in:
linux release using_oss using_backend using_dbox2 using_dvb
using_frontend using_hdhomerun using_iptv using_ivtv using_joystick_menu
using_v4l using_x11 using_xrandr using_xv using_bindings_perl
using_bindings_python using_opengl using_ffmpeg_threads using_live
Sometimes when the backend crashes I just get a line
like:
# fgrep segfault /var/log/messages
Mar 3 09:22:22 mogens1 kernel: mythbackend[16969]: segfault at ce631207
eip 0063bf94 esp abffcf1c error 5
Mar 3 09:23:27 mogens1 kernel: mythbackend[17088]: segfault at 1830c0b9
eip 0063bf9a esp bff9a71c error 4
Sometimes I get a more detailed error message in
/var/log/mythtv/mythbackend.log:
