livetv mythbackend crash when tv show ends/starts

[af7567]

Hi,
I am using mythtv 0.27.4 and kodi 14.1 running on slackware 14.1 32bit. Sometimes when I am watching live tv, mythbackend will crash when the current TV show ends and the next one starts. 5 minutes later mythlogserver segfaults. I have tried running mythbackend with debugging messages and in gdb but I haven't been able to get it to crash then. Has anyone else had a similar problem? I haven't been able to find anything on the forum.

my mythbackend log only shows:

Code: Select all

before ending, and mythlogserver:

which looks ok, but...

Code: Select all

Obviously I will need to get more debug info to really find out what is causing it, but I was hoping someone might have had a similar problem and had some idea of what I could try because whenever I try debugging it I can't get it to crash .
