Event ID: 29106 on RMS Server after upgrade to CU5

After an upgrade of the RMS from SCOM 2007 R2 RTM to SCOM 2007 R2 CU5 EventID 29106 started to appear in the OperationsManager EventLog every 5-15 minutes. The solution was to flush the HealtService.
1. Stop the System Center Management Service.
2. Rename the folder “Health Service State” in C:Program FilesSystem Center Operations Manager 2007.
3. Start the System Center Management Service.
