Provide the backtrace (at least CRASH lines).

It's not fixed, still get server crash while clicking on debug tab. As i said there isnt anything in logfile.

There should be CRASH lines in log, but I don't know which platform do you use.

Using arm version on BananaPro, self compiled. I will look at log again.

Nothing in my syslog, many entries from Tvheadend, but no crash entry.

Do you compiled tvh with execinfo?
$ grep EXECINFO .config.mk CONFIG_EXECINFO = yes
Also, install addr2line to resolve addresses too (binutils package).
Try to run tvh directly from the command line .

And - do you have something in 'dmesg' ?

It crashes also on RPi2, with build HTS Tvheadend 4.1-1008~gc8fcc70

Nice, but we don't know what caused the crash without debug info.

I'm no linux specialist, maybe you have some tipp how to get the necessary debug info?

The backtrace is best to find where the code crashed.

Didn't get that managed, i followed the instructions but tvheadend didnt produce any debug core file or something else, maybe i didnt find that. Maybe i need more detailed instructions how to do backtrace...

Could you try to run tvheadend from cmdline and look, if you see the crash ?
tvheadend -c <cfgdir>
Updated by Nihil Baxter over 9 years ago
Next try, started from commandline, did debugging things from wiki page, produced crash but still no core file in tmp folder. Maybe i did something wrong...

Hi,
I have the same problem with the debug tab. Tvheadend crashes instantly when you hit the debug tab menu.
Here is what I did:
sudo -u hts tvheadend -l /home/mw/tvhlog --debug --trace --dump --uidebug
wait and start tvheadend webui, move on to configure and hit debug tab....crash.
The dump and log files are attached.
Hope this can help you.
Cheers
Moe
