Usermode core files are generated when a user mode process crashes. They are located in the $CPDIR/var/log/dump/usermode directory on the Security Gateway or Security Management server. The core files can be used to analyze the cause of the crash and troubleshoot the issue. The core files are named according to the process name, date, and time of the crash. For example, cpd_2023_02_03_16_40_55.core is a core file for the cpd process that crashed on February 3, 2023 at 16:40:55
