Initial Comment:
Hi

I just found a core file generated by opensips on one of our servers which used to be pretty stable.

Core was generated by `/usr/sbin/opensips -P /var/run/opensips.pid -f /etc/opensips/opensips.cfg'.

main.c compiled on 15:18:52 Sep 28 2012 with gcc 4.4.6

I have no idea what happened. Maybe someone has a theory.
