I did not experienced this so far. You can generate a backtrace with 
killall -SIGABRT kamailio for all processes, or kill -SIGABRT $kamailio-PID.

If you would like to trigger it from the script, there are also some functions 
available in the cfgutils module that implement this, "abort()".

Cheers,

Henning
