[Kamailio-Users] OpenSER 1.3 crash - sr-users

14 Sep 2008

Hi guys!

Posted this to the dev list, but I'm not sure if that's the right forum.
Looking at the posts there, it's more about patches and dev stuff (hence
the name). Hoped to get some feedback on a crash I had a week ago, now
I'm trying it here. :)

We've been running OpenSER (1.3.0 ntls, compiled for x66_64) for quite a
while now and only had a crash once. We suspected then that this was
caused by hitting the max_while_loops for a while (never happened again
after fixing the max-while-loops). Now I had a crash and the backtrace
looks like the following. Do you guys have any pointers on what is
causing this?
