"0x000000D1" and "0x000000C9" Stop errors when Message Queuing moves unsent messages to a dead-letter queue in Windows 7 or in Windows Server 2008 R2

Consider the following scenarios.�

Scenario 1

• You install Microsoft Message Queuing (also known as MSMQ) on a computer that is running Windows 7 or Windows Server 2008 R2.
• Messages are held in a queue. For example, messages are held in the queue when the applications that receive the messages are unavailable.
• Dead-letter functionality is enabled on the queue so that Message Queuing can move unsent messages to a private dead-letter queue.
• A message is not received by an application, and a time-out occurs when the message is sent again.
• Message Queuing moves the message to the dead-letter queue in a transaction.

In this scenario, the computer crashes. Additionally, you receive a Stop error message that resembles the following: Notes

• This Stop error describes a DRIVER_IRQL_NOT_LESS_OR_EQUAL issue.
• The parameters in the Stop error message vary, depending on the configuration of the computer.
• Not all "0x000000D1" Stop errors are caused by this issue.

Scenario 2

• You install Microsoft Message Queuing on a computer that is running Windows 7 or Windows Server 2008 R2.
• Messages are held in a queue. For example, messages are held in a queue when the applications that receive the messages are unavailable.
• Dead-letter functionality is enabled on the queue so that Message Queuing can move unsent messages to a private dead-letter queue.
• You enable the Driver Verifier on the computer.
• A message is not received by an application, and a time-out occurs when the message is sent again.
• Message Queuing moves the message to the dead-letter queue in a transaction.

In this scenario, you receive a Stop error message that resembles the following:
Notes

• This Stop error describes a DRIVER_VERIFIER_IOMANAGER_VIOLATIONL issue.
• The parameters in the Stop error message vary, depending on the configuration of the computer.
• Not all "0x000000C9" Stop errors are caused by this issue.

This issue is caused by a read access violation that occurs when the messages are sent from outgoing queues to dead-letter queues.
