Memory Leak Retrieving OLE Property Values with Service Pack 2

• Microsoft Windows NT Workstation version 4.0 Service Pack 2
• Microsoft Windows NT Server version 4.0 Service Pack 2

SYMPTOMS

Applications that retrieve OLE property values from a file's property store exhibit a gradual increase in memory usage. For example, a program that opens a file's property store, retrieves a property value, and then closes the property store 100 times might see its working set grow by 4 KB as a result of this problem.

The problem described here exists only with Windows NT version 4.0 with Service Pack 2 applied.

CAUSE

A function in Ole32.dll does not correctly delete all the resources it allocates on behalf of the application reading the OLE property values.

RESOLUTION

Obtain the hotfix referenced in this article.
