Core dump analysis, pointing out "Problem seems like a race condition with the APM Introscope agent during policy server Startup / shutdown - likely accessing a pointer that became NULL during shutdown.".

How to Enable Core file on UNIX.
How To Enable Core Dumps In RHEL
1. Edit /etc/security/limits.conf, notice this is set to all processes but if you have a process running as a service account replace the * with the service account (example smpolicysrv). You will have to restart the process for this change to go into effect.
# vi /etc/security/limits.conf
#* soft core 0
* soft core unlimited
2. Edit /etc/sysctl.conf and add where to put the core file and any naming standard.
# vi /etc/sysctl.conf
kernel.core_pattern = /tmp/core-%e-%s-%u-%g-%p-%t
fs.suid_dumpable = 2
%e is the filename
%g is the gid (groupID)the process was running under
%p is the pid of the process
%s is the signal that caused the dump
%t is the time the dump occurred
%u is the uid the process was running under
3. Edit the /etc/sysconfig/init and set a core file limit.
# vi /etc/sysconfig/init
4. Check core status – validates core locations
# sysctl -p
### Additional insights
-You may need to specify the command 'ulimit -c unlimited' before you invoke the policy server process and reproduce the crash in order to obtain a core file with the crash.
-Also check to be sure you know where the cores will be located via the 'sysctl -p' command.
-You may want to reproduce the issue 3 times so we can be sure all crashes are from the same issue.
-Pkgapp utility should be run against core files in the location the cores where initially generated.(Do not move cores to different directory before running pkgapp)
