In Microsoft Message Queuing, also known as MSMQ, messages may accumulate in a transactional queue if the following conditions are true:
When multiple senders send transactional messages to the same queue, message #n+1 may become available before message #n. If a reader reads from a queue by using a cursor, the reader may skip message #n. If this problem occurs, it may appear that data has been lost. However, what has occurred is that the queue cursor has advanced. Subsequent reads will not retrieve the message that was initially skipped unless you restart Message Queuing.
