SYMPTOMS

Server applications may unexpectedly stop accepting connections.

CAUSE

This behavior is due to a bug in the Msafd.dll file. The bug can prevent the replenishment of the listen backlog when a failure occurs during the registering of memory on a freshly accepted connection. When enough of these failures occur, the Msafd System Area Network (SAN) backlog eventually goes to 0, and Msafd starts rejecting all incoming SAN connections.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
