Hello Stagg,

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?
this has to be definitely
fixed if still applies -- thanks for
troubleshooting. Can you get the latest version of 1.5 branch and test.
There were some sanity checks added to dialog module that might solve
this one as well.
Cheers,
Daniel
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.
