This is because statistics rely on incQueuedEvent() and decQueuedEvent() assuming queue is empty when mule starts. If persistent queue is used this may not be the case leading to incorrect stats.

At first sight this seems to be just a case of using existing queue size when initializing service statistics rather than 0. On the other hand I'm not sure how this would play with the other statistics that calculate averages based on this value.
