BUG #: 50000387 (SQL Hotfix)



SYMPTOMS
You may experience an increase in memory usage in an application that uses Microsoft XML Core Services 6.0 (MSXML6).



CAUSE
The increased memory usage occurs because of an increase in document and semaphore handle counts.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
This issue occurs because of a mismatch in the AddRef and Release counts in the MSXML6 node locking code. The mismatch in the AddRef and Release counts may cause a document to be released incorrectly. When the document is released incorrectly, an access violation may occur. However, the primary symptom may be a large increase in memory usage that is followed by a slower increase in memory usage.
