Pretty annoying problem :(
Here's how I enable core dumps on linux installs in sysctl (reboot required):
fs.suid_dumpable = 1
kernel.core_pattern = /tmp/core.%e.%u.%t
kernel.core_uses_pid = 1
On a live system (no need to restart):
echo 1 > /proc/sys/fs/suid_dumpable
echo 1 > /proc/sys/kernel/core_uses_pid
echo "/tmp/core.%e.%u.%t" > /proc/sys/kernel/core_pattern
Hope that now you will be able to "enjoy" the core dumps :-/

Ovidiu Sas

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!
