Hi,
I'm seeing huge number of Stale Warnings in the nagios log for a particular service.
How to get rid of this.?
For this service some times notifications are not sent when it changes from critical to ok state.

Stale Warnings in my log files:
Jan 24 11:33:16 chcrsoch601 nagios: Warning: The results of service 'Windows Automatic Services' on host 'chcrochs927.orange.ch' are stale by 0d 0h 1m 0s (threshold=0d 0h 1m 0s). I'm forcing an immediate check of the service.

Thanks in Advance..

Stale errors are when a passive check has not returned a result in a set amount of time, defined by freshness_threshold. If freshness checking is enabled, nagios will perform an active check of the service (or possibly the host) to determine the state.

Do you notice any pattern of when the notification does or does not go out?
