FIX: Microsoft Message Queuing service stops responding when the client application performs multiple remote reads (884557)


The information in this article applies to:

  • 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.

RESOLUTION

A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing.
