Re: [Astlinux-users] Asterisk Segfault in app_queue.so

[Michael K. <mic...@ip...>]

Thanks Michael. Unfortunately this is Asterisk 13 which I am regretting moving to, but 11 LTS has ended so I should be making the move.
This is currently the only site that I am using Queues and I have not got ant segfaults on any of my other Asterisk 13 boxes (yet!).

Regards
Michael Knill

Hi Michael,

no, you can't get a backtrace directly within AstLinux.

Therefor Asterisk would have been compiled with "asterisk-makeopts: MENUSELECT_CFLAGS=DONT_OPTIMIZE BETTER_BACKTRACES".
And Asterisk would needed to be started with the "-g" option. A debugger and a lot of free disk space is needed as well :-(.

More information:
https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace

Try to figure out if something special has happened at that time (or shortly before). Which Asterisk version, how many concurrent calls? 
In Asterisk 11 I rarely have seen segfaults of Asterisk.
