- Microsoft Message Queuing 3.0
SYMPTOMS
When your Microsoft Message Queuing client application performs multiple remote reads from a Microsoft Windows 2003-based computer, the Transmission Control Protocol (TCP) connection count on the remote computer that is running the Message Queuing service increases until the Message Queuing Server service on the remote computer stops responding.
CAUSE
This problem occurs when the Message Queuing service holds a TCP connection after the Message Queuing service receives a request, but the Message Queuing service does not process the request in a timely manner. Because of this behavior, the TCP connection count increases until the system runs out of resources.
