Thanks.

The jconsole worked great... but the JMSToolBox couldnt connect in any
variation...
Either way the jconsole did the work!

I see this strange behavior...

It seems like some queues are getting to their limit (posting only 2 out of
a dozen more or less):

2016-12-24 20:34:50,065 | INFO  | ActiveMQ NIO Worker 3089         | Queue

Of course... the flow control is enabled as can be seen :)

The issue is that starting this point - NO MESSAGES at all are getting any
longer in the queues.
Even few hours after the limit reached, when I check in the jconsole I can
see that the queue is empty, but no new messaged are getting in the queue.

Did anyone see something like that? once reaching the limit then no new
messages even if queue is not full?
Can it be that the flow control stops the producer, but not telling him to
continue?

additional log I saw is few minutes after with this error:

2016-12-24 20:41:37,520 | ERROR | ervice[externalBroker] Task-1080 | Queue      
                     
| 177 - org.apache.activemq.activemq-core - 5.7.0.1-SNAPSHOT | expired
waiting for space..

I assume the queue was full for a while, but dont cause if such thing
shutting the queue down or doing anything like that...

Hope you have some sights on that :)

Thanks a lot!
