Loss of Cluster Data/Monitoring at same time each day




I'm seeing a loss of data and Cluster Probe health warnings every day at the exact same time. It starts about 2:03 AM and lasts about 3 minutes. During this time I see sensors with "unknown" status and Cluster Probe Health = DOWN with warning: "182 (Probe Interval Delay WMI) is above the error limit of 100 . WMI Sensors of this probe can not be scanned in their specified intervals. Try longer intervals or distribute load over probes.".

It just looks like all monitoring fails or stops for 3 minutes each day at that time. Any ideas what this could be?

What version are you currently running? Are any scheduled tasks taking place at this time? Reports, auto-discoveries, etc.?

Version: There are no scheduled tasks or reports.

The only thing that I'm seeing is an event in the Windows Event log at almost the exact time as the problem starts:

Event ID #1 Source: Kernel-General Level: Information User: System

"The system time has changed to ?2011?-?01?-?26T07:03:52.173000000Z from ?2011?-?01?-?26T07:01:11.481390000Z."

There are also some entries right before that one related to the "Windows Modules Installer Service".

None of these are warnings or errors though.

Server is running OS: Windows Server 2008 R2 Enterprise (as a VMware virtual machine).
