SYMPTOMS
You may experience a deadlock in MSXML 4.0 or MSXML 4.0 Service Pack 1 (SP1) under stress while you make a change to the nodes of an XML free-threaded Document Object Model (DOM) document. This problem becomes evident when several threads are blocked on a semaphore object and your computer stops responding.



CAUSE
This problem is caused by overly pessimistic locking in the document locking code in MSXML.



STATUS
This problem was corrected in MSXML 4.0 Service Pack 2.



WORKAROUND
There is no workaround for this problem.
