I think you may need to provide a crash log. If you want an easy way to capture a core dump install corekeeper [it places them in /var/crash]. You can then use gdb to analyse.

This is crash with tvheadend_4.3-187~gf46a6c2_amd64.deb
GDB is mystery for me, its no easy as creating full network infrastructure for ISP, which i can do with eyes closed

Updated by Just to add, I have the same problem since a few days. (I usually update daily, I haven't checked since which version this problem started, but I think it's about two days ago.) Running Debian x64 ('stretch'), 4.3-193~ga4ff519. Also with a ddbridge module for a satellite receiver.

I guess crash logs / core dumps etc will show the same as in the original bug report, but if you want mine too, let me know.

What is a tvh:mi-table as module in program, what it do and with who communicate?
Updated by Jaroslav Kysela over 7 years ago
Guys, if you like to report a crash, always install the dbg version of package as first and provide the CRASH lines from tvh log with the proper symbols (function names). It really makes my work faster, because in most cases, I see the problem on the first look. Analyzing the crash core files is more time consuming.
OK, going to look to the core file one more time.
Updated by Jaroslav Kysela over 7 years ago
I'm not able to analyze the core (another distro, another ld-linux.so). Provide output for the debug version of tvh binary (install tvheadend-dbg_4.3) like:
$ gdb <tvh_binary> <core_file> (gdb) set logging on (gdb) set pagination off (gdb) thread apply all bt full (gdb) quit
The backtraces should be in the gdb.txt file.
Or just look for CRASH lines in tvh log (or syslog if configured). The log file should be better.

Im currently with tvheadend-dbg_4.3-193~ga4ff519_amd64.deb
service tvheadend start
not work
command
tvheadend -u tvh -g video -s -c /home/hts/.hts/tvheadend/
not work as expected it try to use current user
Updated by Mark Clarkstone over 7 years ago
I hope this helps, here is the log from saen's crash2.gz file
Removed the log as it isn't useful - see below.
Updated by Jaroslav Kysela over 7 years ago
Thanks Mark, but the used binary is without debugging symbols (function names), so the backtrace is not useful. I updated https://tvheadend.org/projects/tvheadend/wiki/Debugging to show the incorrect/correct CRASH lines.
Sean Sean acro: If you only write 'things does not work' without any info from tvh or system logs, I cannot really help you.

Ah crap, sorry! I wondered why I was getting mostly missing symbols, I assumed it was due to being a slightly different system [my inexperience is showing :p]

@Jaroslav Kysela
why not make service start as debug with all that things with you need to analyse crashes
aka
service tvheadend (start|restart|stop|debug)
Updated by saen acro over 7 years ago
- File crash3.tar.gz crash3.tar.gz added

What is a tvh:mi-table as module in program, what it do and with who communicate?
there is noting in wiki i'm just curious,
give us some short description why bug happens?
Updated by Jaroslav Kysela over 7 years ago
