SYMPTOMS
In Windows NT 4.0, a nonpaged pool memory leak may occur when functions like IoReadPartitionTable or DeviceIoControl attempt to read a partition table. The Microsoft Developer Network explains these functions at:

http://msdn.microsoft.com



CAUSE
This problem occurs because memory allocated when reading the partition table may not be freed in the event that an error, such as STATUS_DEVICE_BUSY, is returned.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

To resolve this problem, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.
