Q269819: Deadlock Deleting Attribute Stream During File Creation

Article: Q269819
Product(s): Microsoft Windows NT
Version(s): 4.0
Operating System(s): 
Keyword(s): kbWinNT400PreSP7Fix
Last Modified: 08-MAY-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
- Microsoft Windows NT Server, Enterprise Edition version 4.0 
- Microsoft Windows NT Workstation version 4.0 
- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

Windows NT 4.0 may stop responding (hang) or deadlock randomly during heavy file
input/output (I/O) operations on a partition that uses the NTFS file system.

CAUSE
=====

This behavior is caused by an untimely attempt to remove the attribute list
stream for an NTFS file while other streams still exist for the file control
block (FCB).

When Windows NT 4.0 hangs, there are two threads involved. One thread is in the
process of opening the attribute stream and waiting for the FCB lock. The other
thread has the FCB lock and is closing the stream, but cannot close it until the
reference count is zero.

RESOLUTION
==========

correct the problem described in this article and should be applied only to
