Team,
Some notes state core dumps need to be enabled to isolate issues with the Linux releases of the Provisioning Server.
Provisioning Servers on UNIX - CA Identity Manager - 14.0 - CA Technologies Documentation
The below process shows where to re-enable core dumps for the imps userID.
Update note about disabling or enabled core dumps in /etc/security/limits.conf
Example: To disable ALL core dumps on a Linux server
* hard core 0
To enable core dumps ONLY for uid=imps (with unlimited size)
imps hard core unlimited
Restart the system or re-issue the sysctl command(s)
Example:
# Enforce updates without reboot
/sbin/sysctl -p
/sbin/sysctl --system
Cheers,
Alan
