Is the trace from running kamailio 4.1? What is the output of: kamailio -v Cheers, Daniel On 04/12/14 17:23, Daniel-Constantin Mierla wrote: Btw, you need to install dbg symbols package, in case you installed from some deb/rpm.

Typing bt full now sent me into something like “more” so I had to copy everything by hand, like 46k lines. So I searched the web for a non interactive method and came up with this. If it is not ok, please tell me how to get the “bt full” string out of this interactive gdb shell. I will provide you with the output of gdb itself, I missed that in the last mail.
