[SR-Users] Kamailio 1.5.5 No TLS Segmentation Fault

[Stagg Shelton]

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
