KB951526 (Hotfix) – The Root Management Server (RMS) of System Center Operations Manager 2007 Service Pack 1 becomes unstable or unusable if a management pack is imported

The following Kb has been recently published and a hotfix is available. See  http://support.microsoft.com/kb/951526



Consider the following scenario:

•You import a management pack to monitor certain network devices in a Microsoft System Center Operations Manager 2007 Service Pack 1 environment.

•You perform a network device discovery by using Simple Network Management Protocol (SNMP).

In this scenario, you may receive one or both of the following error messages:
Error message 1

Health service host process has stopped working

Error message 2

Health service Host process encountered a problem and need to close

In this scenario, the OpsMgr Health Service is still running correctly. However, the Root Management Server (RMS) becomes unhealthy or unusable. Additionally, the following event is logged in the Operations Manager log on the server on which you perform the network device discovery:

Event Type: Error
Event Source: HealthService
Event Category: Health Service
Event ID: 4000
Date: Date
Time: Time
User: N/A
Computer: ComputerName
A monitoring host is unresponsive or has crashed. The status code for the host
failure was 2164195371.
Problem signature:
Problem Event Name: APPCRASH
Application Name: MonitoringHost.exe
Application Version: 6.0.6278.0
Application Timestamp: 47b71437
Fault Module Name: HealthServiceRuntime.dll
Fault Module Version: 6.0.6278.0

A defect in the SNMP networking module causes the HealthService service to become unstable or to crash. Therefore, the Root Management Server becomes unstable or unusable.
