SCOM RMS flooded with 29106 and 21042 events

Hi all,

I am facing strange issue with the SCOM 2007 R2 environment with clustered RMS after  deleted and imported a management pack. We are seeing events 21042 and 29106.

1)   Stop System Center Management service.

2)    Renamed the “Health Service State” folder in the cluster disk

3)   Restart System Center Management service.

2.   Restart the following services: 

System Center Management service

System Center Management Configuration service

System Center Data Access service

But No luck still getting the same events getting flooded.
