[SR-Users] Kamailio stops processing requests mid script

Hi Daniel,

I've tried with apparmor disabled unfortunately the same issue happens.

I've sent you privately the output of the kamctl trap. I personally don't
think it's Kamailio's fault per se, this is on a standard debian 11. I'm
just lost and don't really understand what the hell is going on.

Thanks, I appreciate your help with this.
Joel.
