> When a message is rerouted several times, the broker's used memory increases rapidly. This is counter-intuitive, considering that the messages themselves are only passing from one queue to another. There is no evidence of a leak, however, only a large growth in consumed memory.
> An investigation has shown that the process of clearing traces from the message when rerouting (whether they exist or not) causes the message and its frames to be copied (for reasons of avoiding locks on the message, which can affect performance).
