Tvheadend

Hi,

my tvheadend crashes every 10 minutes. I'm running the SVN version and problems started to appear about a month ago.

Looks like this in my syslog:

Any idea what it tries to do every 10 minutes?

EPG grabber perhaps? If you install the debug package it should give more info. you may also want to try running it via gdb & get a full trace.

Thanks for the tip!

I disabled the "EIT: DVB Grabber" (in Configuration - Channel/EPG - Over-the-air Grabbers ) and voila, the crashes disappeared!

So you can close this bug!

well the EIT grabber should not Crash at all, which channel / transport stream is tvh tuning to bevor it crashes? Or maybe you could grab the complete stream for somebody to analyze the problem.

Exactly, it would really help if Martin would post a gdb trace, so someone (more than likely perexg) can take a look & find out why it's crashing.

You'll get a proper stack trace if you install debug symbols and reproduce the crash. If you've compiled from source, make sure you have --enable-debug, if you installed a .deb package, make sure you install tvheadend-dbg.
