Or I'm not correct ? Well, yes, IF you have configured it this way, but not everyone wants redistribution. Secondly, this puts a big strain on the first node - the operation to merge queues in the database is fairly heavyweight, also it will have to load all these message on one node (memory issues), then all these messages have to be shifted off this node - which is very CPU and IO intensive.
