Hi Timo,
I have not tried the latest SVN yet. My system just did another core again today. The backtrace seems to show it at the same location. Below is the backtrace from today. If grabbing the latest SVN is the only chance of stopping this behavior I can do that, but I have to be as careful as possible to try and ensure that new anomalies are not introduced as a result of a code change. Is the information from the backtrace even helpful for identifying the root cause of the issue?

Hi Stagg,
with regards to the failing function, there was a bugfix in the dialog module which, unfortunately, didn't make it into 1.5.5 in time (revision 6049). Could you try the latest SVN of 1.5 and see if it solves the issue?
Thanks.
Cheers,

Hello,
We have been having a problem with Kamilio faulting and dumping core files on occasion. I have not been able to reproduce the failure at will, but notice the back trace seems to point toward actions with the dialogue. Below is from a backtrace of a core file from just a few minutes ago. Can anyone determine what may have caused the system to error and stop processing?
Thanks Stagg
