Accidently replied directly to clause. So here is a summary:
Sent core dump and system spec info like openser ver.
Klaus suggested upgrading to the latest openser 1.2 svn code, trying again,
include pert part of openser.cfg, sip packet capture, and making a bug
report.
So I'm now using latest svn of openser 1.2 as of 11/12/07 on a different
server (the backup server)
Problem still persists.
gdb of one of the core dumps is included below.
Below that is a nuterized (my personal server and gateway info cleaned out)
openser.cfg
Thanks
Dave
Below is the gdb of one of the cores:
Using host libthread_db library "/lib/libthread_db.so.1".
