SYMPTOMS
Messages that are sent to Microsoft Message Queuing (also known as MSMQ) by using the MSMQ-MQSeries Bridge may be permanently lost if the Bridge does not open the Message Queuing queue.



CAUSE
When the MSMQ-MQSeries Bridge does not open a queue because of an error other than &quot;Access Denied,&quot; &quot;Queue Not Found,&quot; or &quot;Illegal Format Name,&quot; the Bridge closes the relevant pipe, discards the messages that it read from the MSMQ-MQSeries Bridge transmission queue, and shuts down its connection to the MSMQ-MQSeries Bridge without closing the associated transaction. By default, the MSMQ-MQSeries Bridge commits its internal transactions if the connection is closed gracefully. When the internal transactions are committed, the messages are removed from the queue. The MSMQ-MQSeries Bridge cannot resend the messages when the connection to Message Queuing is restored because the messages were removed.
