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@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:

Best regards,
Ozren
