[SR-Users] possible bug with dialog module

[Daniel-Constantin Mierla]

Hello,

are you using the latest git version of branch kamailio_3.0? It was a 
fix to dialog after the 3.0.0 release, adding some sanity checks for 
broken messages:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=787fabb1e0085355aa1eeb77d5f17e7940f4ed3c

On the other hand, I see you got a core dump file:
Apr 21 10:19:57 kamvm-1 /usr/local/sbin/kamailio[28507]: ALERT: <core> 
[main.c:722]: child process 28511 exited by a signal 11
Apr 21 10:19:57 kamvm-1 /usr/local/sbin/kamailio[28507]: ALERT: <core> 
[main.c:725]: core was generated

Locate the core file and sent the backtrace. The core is either in root 
'/' folder or in working directory (if you provided by -w parameter).

Use the gdb:

gdb /path/to/kamailio core_file

then do bt and send here.

Thanks,
Daniel
