AFD Executive Worker Thread Causes Excessive Nonpaged Pool Use

 Last reviewed: December 18, 1997
Article ID: Q164823
The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0

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 4.00. A supported fix is now available, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
