Hi Daniel,
here is the backtrace:

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.
I've repeated scenario described in the first mail: user tries to join in a
private room without getting an invite first.
Best regards,
Ozren

Hello,
can you get the core dump and send the backtrace?
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).
Cheers,
Daniel

Hi,
there is a bug in IMC module that crashes Kamailio.
Here is the scenario: One user (pero(a)abc.hr) creates private chat room (
chat-999(a)abc.hr). Other user (oz(a)abc.hr) tries to join the chat-999(a)abc.hrby sending
#join. Kamailio crashes at that point. Here is the log:
