Opened: May 11, 2023

Severity: 2-Critical


If there are a lot of LTM or GTM database monitors in use, then the DB_monitor process may, in extremely rare circumstances, inadvertently end the processes that are not intended to be stopped.


Some linux processes may unexpectedly end.


Many database monitors, frequent PID reuse. This should be extremely rare.


Preiodically clean up with PID files: find /var/run/ -iname \*SQL__* -mtime +1 -exec rm -vf '{}' ';' and/or increase the number of available Linux PIDs: echo 4194304 > /proc/sys/kernel/pid_max
