Nagios Support Forum

My monitor engine event queue since today is acting up, or at least the system doesn't seem to be processing checks.

* I tried checking the DB Health
* I dont see any errors on on the LOGs, including the gearmand and nagios.log
* I tried restarting nagios and the database.
* File Systems look OK.
* tried running a repair database script, everything came back clean.
* rebooted the server.
* on the nagios.log file, I see a lot passive check being process but not a lot active checks
* all workers seem OK

any of the above don;t seem to help

gearman_top does seem to report some activity, but I don't see a lot activity.
