As per further investigations, I have some logs to post. It's odd because the logs says that the message has been delivered but the consumer sisn't receive any. And in the next checkpoint activemq says that there is a pagedInMessage, where there shouldn't be any, right?
What is the difference between dispatched and delivered?
