Hello,<br>
<br>
did you get only one core file? This one seems from the main process
when it discovered that a SIP worked crashed.<br>
<br>
If you got more than one, send the backtraces from the other core
files. If you got only one, please enable one core file per process
and re-do it again.<br>
<br>
See last part of:<br>

I'm not sure if I got the right thing. I got it with gdb
/usr/local/kamailio-ozren/sbin/kamailio --core core and called bt
in gdb.<br>
<br>
I've repeated scenario described in the first mail: user tries to
join in a private room without getting an invite first.<br>
<br>
Best regards,<br>
Ozren<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>
there is a bug in IMC module that crashes Kamailio.<br>
<br>
Here is the scenario: One user (<a
moz-do-not-send="true" href="mailto:pero@abc.hr"
target="_blank">pero@abc.hr</a>) creates private
chat room (<a moz-do-not-send="true"
href="mailto:chat-999@abc.hr" target="_blank">chat-999@abc.hr</a>).
Other user (<a moz-do-not-send="true"

tries to join the <a moz-do-not-send="true"
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>
