After enqueuing messages into the queue, they never dequeue from the Queue until i restart Jboss, taking into account that other messages flow normally. i.e. all of the messages i send to the queue are the same, but some of them don't come out. I check them under the "Hypersonic DBStorageManager", and I find them, then I have to restart JBoss so they come out.
