[SR-Users] Kamailio fails to generate core dump

Hi,

I recently had a simultaneous crash on three production instances of Kamailio. Unfortunately, I have not been able to get to the bottom of the issue because Kamailio refused to produce a core dump:

Dec 30 15:37:29 xxxxxx /usr/local/sbin/kamailio[13743]: ALERT: <core> [main.c:784]: handle_sigs(): child process 13763 exited by a signal 11 Dec 30 15:37:29 xxxxxx /usr/local/sbin/kamailio[13743]: ALERT: <core> [main.c:787]: handle_sigs(): core was not generated

I do not have disable_core_dump=yes (default is no), and checked ulimits for limits on core file size. Kamailio was running as root, and there was no limit.

What are the other reasons why Kamailio may not generate a core dump in such a case?

Thanks!
