[rabbitmq-discuss] Zero message rates in management interface

All of our RabbitMQ 3.3.0 queues are incorrectly reporting message rates or number of queued messages for the previous ~15 seconds in the web management interface.

This can be seen by scrutinizing the following two images. In the first image, http://i.imgur.com/LiFFyTw.png , at 10:21:30, originally a zero message rate is reported, and the the queue size reported is incorrectly still at the same value from fifteen seconds ago. 

In the second image, http://i.imgur.com/9hxhKd6.png , you can see that the management interface now displays the correct data for the previous image's time, 10:21:30, and furthermore, the problem is continuing to occur at 10:22:00. It continues on this way, never showing the data for the previous few seconds, but eventually, after enough time has passed, it will display it.

Problem is the same across browsers.

Any ideas? Thanks much!
