Hello again and sorry for answering so late :) I was refreshing jconsole manually and it did not show any updates until around 10 seconds later (this seemed to vary a little bit).
In the tests that we have done there were no consumers for the queue that we've tested. After activating a consumer on the queue, everything worked as expected. ActiveMQ was refreshing the MemoryUsageByteCount with every message that was dequeued (no more delays) and we had received the ResourceAllocationException. I don't know exactly why this happens. Could this be a bug?
