Hello,

what operating system do you have? How did you start kamailio?

Maybe you can try to set the limit in the system, via:

/etc/security/limits.conf

Do you get other messages from the kernel (should be in the default syslog file), it typically points to file and the instructions pointers.

Cheers,
Daniel

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!
