However, if I only put one consumer pointer in the QueuedMessge that also mean I can only update one consumer's position property when requeue the message. I am thinking that if we requeued a message, does it also mean that this message is available to ALL consumers? so I need to update the position property to ALL consumer. Am I correct? If my assumption is correct, then I need to find all the functions that invoke Queue::requeue and insert some code before calling it. was (Author: chenta): After some experiment, add a point to consumer in QueuedMessage can solve the problem and past the python test.
