  • Microsoft SharePoint Portal Server 2001

SYMPTOMS

When you create and run a custom program in SharePoint Portal Server that contains a call to get_Count on the Fields collection of an IKnowledgeDocument, memory usage may increase steadily on the server. This may eventually cause the server to stop responding (hang).

RESOLUTION

This problem was first fixed in a hotfix that is now contained in a service pack. If you have installed SharePoint Portal Server 2001 Service Pack 3 or a later service pack, you do not have to apply the hotfix.
