Hello,<br>
<br>
can you get the core dump and send the backtrace?<br>
<br>
Be sure you have 'ulimit -c unlimited', working directory (-w
option) set to writable path and you don't run it in chowner (no -u
or -g parameters).<br>
<br>
Cheers,<br>

<br>
there is a bug in IMC module that crashes Kamailio.<br>
<br>
Here is the scenario: One user (<a href="mailto:pero@abc.hr" target="_blank">pero@abc.hr</a>) creates private chat
room (<a href="mailto:chat-999@abc.hr" target="_blank">chat-999@abc.hr</a>).
Other user (<a href="mailto:oz@abc.hr" target="_blank">oz@abc.hr</a>)
tries to join the <a href="mailto:chat-999@abc.hr" target="_blank">chat-999@abc.hr</a> by sending
#join. Kamailio crashes at that point. Here is the log:<br>
