Internet Information Server 3.0 May Stop Responding to Client Requests (235611)


The information in this article applies to:

  • Microsoft Internet Information Server 3.0
This article was previously published under Q235611

SYMPTOMS

Internet Information Server (IIS) 3.0 may stop responding to client requests, making it necessary to stop and restart the IIS 3.0 services.

CAUSE

When IIS 3.0 attempts to close a socket it first shuts down the connection, notifying the client that it is closing its side of the connection. While in this state, it is still possible for the client to continue to send data. Currently, there is no time-out, creating the possibility for a misbehaving client program to keep the connection's Web services open indefinitely. If this occurs while IIS 3.0 is cleaning up the connection, all other client requests are queued up. This eventually causes IIS 3.0 to stop responding to any client request.
