I believe that we have discovered why kamailio was core dumping. We
received a 200 OK with SDP back from an upstream that had a mal
formatted Record-Route: header field.
Record-Route: <sip:8.17.32.37;lr=on;did=87e.7defc835>,SUBSCRIBE,NOTIFY
Each time we received one of these packets with the bad RR header,
openser-1.3.4, kamailio-1.5.1, and SVN kamailio from 6/12 each core
dumped at update_dialog_dbinfo. While I understand that the Record-
Route example is bad, and certainly doesn't conform to the RFC. Would
it be possible to do some kind of sanity check on the header and
handle the garbage data error more gracefully?
Thanks

Hello,
there were some recent fixes to dialog, but after 1.5.1 was
released. you have to take the source from svn branch 1.5:
svn co https://openser.svn.sourceforge.net/svnroot/openser/branches/1.5
kamailio-1.5
Install it and try again. Should be fixed, if not, let me know.
Cheers,
Daniel

I've recently tried to migrate my production
environment to
kamailio 1.5.1-notls from openser-1.3.4-notls. I have been working
through some issues, and the most recent issues have been that
kamailio has begun to segmentation fault and core dump. Has anyone
else experienced any similar issues, what other information could i
provide that can be helpful in diagnosing my troubles with 1.5.1.
I have had to fall back to 1.3.4 until i can get this sorted out.
Below is my backtrace of the core dump file.
Core was generated by `/sbin/kamailio -m 1024'.
Program terminated with signal 11, Segmentation fault.
