Cluster Server Slows Down or Hangs When Running Resource Monitor

When you use the Resource Monitor tool on a computer running Microsoft Cluster Server (MSCS), you may notice that the server eventually slows down or stops responding (hangs). You may not notice an immediate drain on resources, but the performance impact could be significant over a long period of time.

A leak in Resource Monitor's own memory causes it to slowly use up all free memory in the computer in order to keep running.

Resource Monitor (Resrcmon.exe) is an MSCS component that monitors the health of each resource through callbacks to the resources and communication with MSCS by using Remote Procedure Calls (RPCs). It also provides the polymorphic interface between generic calls and the specific online operation for that resource.

Clusters are useful in that they simplify the management of servers by allowing an administrator to manage them as a single computer. MSCS has built-in clustering server software in Windows NT Server, Enterprise Edition. As well as easier manageability, MSCS offers improved availability, more cost-effective scalability, and automatic failure detection and recovery. MSCS can also be used to move server workload to balance usage and to provide for planned maintenance without down time.
