SYMPTOMS

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 or in a Microsoft System Center Essentials 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:
Health service host process has stopped working
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
