Hi,
I previously got only one core file, but now that I've enabled one core file per process, I got two core files. Here are the backtraces:

Hello,
did you get only one core file? This one seems from the main process when it discovered that a SIP worked crashed.
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.
See last part of:

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).

Daniel

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