Hi Guys,
We are running kamailio 4.4.6 on debian 8 and not had any issues, however we did suffer a
segfault and a core was generated;
May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: ALERT: <core> [main.c:740]:
handle_sigs(): child process 9575 exited by a signal 11

Is this of any help? Could someone advise what next steps might be?
Should we be looking to upgrade or is there a way to get more detail out of the core
dump?
Many Thanks
Jon
