AFD Executive Worker Thread Causes Excessive Nonpaged Pool Usage (164823)


The information in this article applies to:

  • Microsoft Windows NT Workstation 4.0
  • Microsoft Windows NT Server 4.0
This article was previously published under Q164823

SYMPTOMS

A computer running Windows NT Server may stop responding or report virtual memory errors under high stress situations. Excessive nonpaged usage can be viewed in Performance Monitor.

If pool tagging is enabled, the TCPt and Afde pooltags allocated bytes will rise, exhausting non paged usage.

CAUSE

In cases like these, processes fail to free memory pages once they are done with them. Over time, this leads to a highly stressful situation for a system.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0.

This problem has been corrected in the latest U.S. service pack for Windows NT version 4.0. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
