SYMPTOMS
Occasionally, you may receive a System.Messaging.MessageQueueException exception when you are running an application. The MessageQueueErrorCode property of this exception contains the following error code:

BufferOverflow

The message that accompanies this exception is similar to the following:

Buffer supplied to MQReceiveMessage for reading the message body was too small. The message cannot be removed from the queue, and the message body was truncated to fit the buffer when it was copied to the buffer.

This problem occurs when the following conditions are true:
 * 1) You use the BeginReceive method in the System.Messaging.MessageQueue class to read asynchronously from a local PRIVATE$ queue.
 * 2) The local PRIVATE$ queue is under stress.
 * 3) You call the EndReceive method in the System.Messaging.MessageQueue class to complete the asynchronous receive operation.
