Hi,
The backtrace is not very useful, there are no debugging symbols. You probably installed a kamailio RPM on that machine. Try to compile directly on the machine and reproduce.

Hello,
there should be a kamailio-dbg or kamailio-debug rpm/deb package than can be installed to get the debugging symbols. Install that and grab again the backtrace to get some useful details.
Cheers, Daniel
