FIX: Microsoft Message Queuing service (Mqsvc.exe) exhausts its private bytes when the GetPrivateQueuesByMachine function is called


Microsoft Message Queuing service (Mqsvc.exe) exhausts its private bytes.


This problem occurs when your Message Queuing client application makes repeated calls to the MessageQueue.GetPrivateQueuesByMachine function. These calls are made to retrieve a list of all private queues on a specified computer. Message Queuing does not have the deletion code that is required to remove the lists of private queues.
