Re: [sr-dev] [kamailio/kamailio] Random segfault or general protection crash on siptrace.so module (#2718)

In case someone else runs into this issue -- it was far from transparent, but my best guess is it was caused by some combination of file permission issues. These are the various things on CentOS 7 that were tweaked to allow a core dump

The following combination of things were changed:

/etc/sysctl.d/99-sysctl.conf ``` kernel.core_pattern = /tmp/core.%e.%p.%h.%t kernel.core_uses_pid=1 fs.suid_dumpable = 2 ```

`sysctl --system` to reload kernel parameters

/etc/sysconfig/kamailio ``` DUMP_CORE=yes ```

May be required but unclear: `ulimit -c unlimited`

Tested by running `kill -ABRT <PID of Kamailio Child>`
