SYMPTOMS
After you quit Resource Monitor, the Cluster service may continue to try to restart resources. When this occurs, the cluster may not work, and you may see the following symptoms:
 * Each node sees the other node as down
 * Each node terminates the Resrcmon.exe program
 * Each node keeps trying to bring resources online
 * Each node cannot bring the resources online and blocks, waiting for the quorum resource



CAUSE
This problem can occur if you run out of resource monitors in which to run resources.



RESOLUTION
To resolve this problem, upgrade to Service Pack 4 (SP4) or later if you are using a computer that is running Microsoft Windows NT 4.0. If you are not using a computer that is running Microsoft Windows NT 4.0, verify that you do not have resources set to run in their own resource monitor. Resources that are set to run in their own resource monitor consume an entire resource monitor and reduce the maximum number of resources that a cluster can support.

If the server is a file server, you may want to implement dynamic file shares to share all home folders under a single resource. For additional information about file share resources on a cluster, click the article numbers below to view the articles in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
There is a limit to the number of resources supported on a Server Cluster.

Server Clustering supports up to 930 resources: 15 resource threads multiplied by 62 resource monitors equals 930 total resources.

After you install Windows NT 4.0 Service Pack 4 (SP4), the number of resource threads increases to 27, including Windows 2000, and later 27 resources threads multiplied by 62 resource monitors equals 1674 total resources.
