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

ok, i'll enable debug for now.
but if it's indeed a buggy UA, the dialog module should not have crashed

but instead dropped the dialog/session and moved on, something i think

we need to address to be more resilient.

i hope i catch the culprit when this happens again.

Perhaps in your case you have a buggy UA setting an invalid Contact
header and it causes Kamailio to crash, maybe the reason others have
not detected same issue.

Could you get some SIP traces until the problem occurs again?
or perhaps could you enable the debug?
