SYMPTOMS

On an extremely busy server with over 5,000 connections being made from the server by using the Connect Winsock call, the server may slow down when it responds to requests. The server may eventually stop responding.

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:

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows 2000 Service Pack 1.

MORE INFORMATION

This behavior is known to occur only on proxy servers that are opening and closing large numbers of connections continually. When the Connect function is called, the server must search a table to determine whether there are other connections with the same source and destination. The algorithm that performs this search has been improved; scaling this operation is no longer an issue.
