[Kamailio-Devel] OpenSer 1.3.0 crash

[Robin Vleij]

Hi guys!

Posted this to the user list, but I'm not sure if that's the right
forum. 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? We got another crash, on the same server last Saturday.
I'll attach the backtrace for that one at the bottom.

First backtrace:

Any ideas?
