[SR-Users] kamailio core dumps once every few days

Gents, On a not really loaded kamailio (less than 50 users at the moment), I'm getting a core dump every few days. I've tried multiple verisons of Kamailio, 4.4.x , 4.3.x and also on 5.0.0-dev7 . I can't reproduce it adhoc, but every few days it happens... Is that something someone wants to jump in? grtz, davy Version: version: kamailio 5.0.0-dev7 (x86_64/linux) 7360b0 [New LWP 29728] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
