A customer of mine had several “Idle Minutes Monitor Alert” raised by the Key Management Server MP.
The eventlog for KMS on the KMS Server stated, that there was an KMS request round about every 30 seconds.
So the error was definitiv a false positive.
The treshold for the monitor was default (480 minutes).
I inspected the monitor and saw in the configuration, that the last activity in KMS is stored in the operations manager.
These values are inserted through a scheduled discovery that runs every 15 minutes.
I exported the management pack and had a look on that discovery. There I found an VBS script that does a lot of WMI queries.
As the KMS Server is a Server 2008 R2, and there is a WMI Memory Leak on excessive usage of WMI, I installed the corresponding hotfix and the error was gone.
This hotfix is: KB981314 (http://support.microsoft.com/kb/981314)
Kind regards,
Benedikt
