History

Provide the backtrace (at least CRASH lines).

#2

Updated by Nihil Baxter about 9 years ago

Where did i find that? Not sure what you need, sry ;-)

#3

Updated by Nihil Baxter almost 9 years ago

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

#4

Updated by Jaroslav Kysela almost 9 years ago

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

#5

Updated by Nihil Baxter almost 9 years ago

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

#6

Updated by Nihil Baxter almost 9 years ago

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

#7

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

#10

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

#11

Updated by Nihil Baxter almost 9 years ago

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.

#13

Updated by Nihil Baxter almost 9 years ago

OK, i will look there

#14

Updated by Nihil Baxter almost 9 years ago

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...

#15

Updated by Jaroslav Kysela almost 9 years ago

Could you try to run tvheadend from cmdline and look, if you see the crash ?

tvheadend -c <cfgdir>
#16

Updated by Nihil Baxter almost 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
