APPLIES TO
- Microsoft Message Queuing 3.0
- Microsoft Windows Server 2003 Service Pack 1
SYMPTOMS
When you send a Microsoft Message Queuing 3.0 message between two servers that are running Microsoft Windows Server 2003 with Service Pack (SP1), the message may not be acknowledged. The receiving server seems to be unable to store the incoming message.
Specifically, the following problems occur:
- The sending server keeps sending a transactional message after the 30-second default resend interval. The sending server does not increment the order acknowledgement.
- The receiving server returns the same order acknowledgement and seems to be unable to store the message for unknown reasons.
- The sending server closes the connection and then reconnects. However, the sending server never tries to resend the message.
CAUSE
This problem occurs because of a race condition. A token is used to identify the location of a message in the message list. The race condition allows for this token to be reused for a new message before the old message is removed from the list.
RESOLUTION
Service pack information

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows Server 2003 Service Pack 2.
MORE INFORMATION
When a message arrives in Message Queuing 3.0, the message is put in a list, and an asynchronous write is issued. When the write finishes, the process finds the message in the list and then starts the next step for the message.
Therefore, when the write for a new message finishes, the process looks for the new message in the list. However, the process finds the old message instead. Because the write for the new message never appears to finish, the process stops processing the new message and all the following messages.
New messages keep being added to the list, but the new messages are never acknowledged. The new messages are never acknowledged because the write for the first message in the list never appears to finish.
