Hello,<br>
<br>
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:<br>
<a href="http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=787fabb1e0085355aa1eeb77d5f17e7940f4ed3c" target="_blank">http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=787fabb1e0085355aa1eeb77d5f17e7940f4ed3c</a><br>
<br>
On the other hand, I see you got a core dump file:<br>
<font face="arial, sans-serif"><span style="border-collapse:collapse"><font face="arial, sans-serif"><span style="border-collapse:collapse"><span style="font-size:13px"><div class="im">Apr

<core> [main.c:722]: child process 28511 exited by a signal 11<br>
Apr 21 10:19:57 kamvm-1 /usr/local/sbin/kamailio[28507]: ALERT:
<core> [main.c:725]: core was generated<br>
<br></div>
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).<br>
<br>
Use the gdb:<br>
<br>
gdb /path/to/kamailio core_file<br>
<br>
then do bt and send here.<br>
<br>
Thanks,<br>
Daniel<br>

</div>
<div>i hope i catch the culprit when this happens again.<br>

<br>
Perhaps in your case you have a buggy UA setting an invalid Contact<br>
header and it causes Kamailio to crash, maybe the reason others have<br>
not detected same issue.<br>
<br>
Could you get some SIP traces until the problem occurs again?<br>
or perhaps could you enable the debug?<br>
