STOP 0X0000000A in Afd.sys on Multiprocessor Systems

ID: Q164416


The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
  • Microsoft Windows NT Server versions 3.5, 3.51, 4.0


SYMPTOMS

A multiprocessor computer running Windows NT and using TCP/IP protocol may give the following STOP error message when an application tries to close a socket:

Stop 0X0000000A(0x0000000a,0x00000028,0x00000002,0xf24cc2be)
NOTE: The fourth parameter within parenthesis is computer-specific, and will most likely vary from computer to computer.


CAUSE

The locking mechanisms used in the ancillary function driver (AFD) are insufficient, resulting in one thread of execution canceling the I/O request packet (IRP) that was used by another.


RESOLUTION

To resolve this problem, obtain the hotfix mentioned below. With the hotfix, the AFD driver has been modified to ensure that access to I/O request packet under the above-described conditions is properly synchronized.


STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5, 3.51, and 4.0.

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.
