[SR-Users] Kamailio 1.5.5 No TLS Segmentation Fault

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,

--Timo

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?
