[SR-Users] Kamailio crashes after Contact expires event route

[Daniel-Constantin Mierla]

Hello,

it looks like you can reproduce it, if yes, try to get it write the core
dump file. For that you may have to do:

ulimit -c unlimited

then run kamailio as user "root" (or a user with root privileges) with
-w parameter pointing to a folder where you want the core file to be
saved. Reproduce the issue and it should generate a core file. Grab the
output of "bt full" with gdb from the core file and send it here.

Cheers,
Daniel
