Hello,
we are using a kamailio 3.3.1 version here and suddenly it crashed with a core.
Any point about how to debug this will be appreciated!

Hello,
it seems that the core file of the process that crashed was overwritten by a core dumped by the main process while cleaning up.
Did you get many core files? If not, can you look in the log messages to see if there were some error messages printed at the time of crash?
You should enable one core per pid, usually this is done by:
echo "1" > /proc/sys/kernel/core_uses_pid
Cheers, Daniel
