I am getting this error message via admin email, about 24 per day throughout the 24 hour wall clock
May 15 04:16:34 mail zimbramon[15887]: 15887:err: Service status change: mail.domainname.com logger changed from running to stopped
When I check the var/log, no start message for zimbramon. When I check zimbra status through the terminal console, everything is running (zimbra status). When I check the web admin zimbra status, everything is running.

Is this normal?
