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.
