[SR-Users] 3.3.2 dumps core on unresolvable names

[Måns Nilsson]

Hi, 

I've now twice experienced a core dump in my Kamailio install, where it tries to process an INVITE that is made to a domain name that does not exist. 

Log:

Does this relate to any known issue? Should I just upgrade? 

FreeBSD 9, by the way.
