---------------------------------------

             Summary: Address Memory Used increases by 60% when messages are moved to another queue
                 Key: ARTEMIS-3572
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3572
             Project: ActiveMQ Artemis
          Issue Type: Bug
            Reporter: Daniel Claesén


When I manually move messages from one durable queue to another the address memory used increases by 60%. I expect the address memory used to remain the same as before the messages were moved.

The same thing happens when the broker moves messages automatically from a queue to the DLQ.

Steps to reproduce:
 * Using the GUI in the console:
 ** Create a new multicast address named "mytest"
 ** Select the address and create a durable multicast queue named "mytest"
 * Use the artemis CLI to produce messages. For example like this:
 ** artemis producer --user admin --password admin --url tcp://localhost:61616 --destination topic://mytest --message-count 1000 --message-size 40960 --threads 4
 * Note the reported address memory used in the console
 ** In the example above it is 160.26MB
 * Use the GUI in the console to move messages. For example with the following operation:
 ** moveMessages(String, String)
 *** Keep the filter param empty and enter "DLQ" in the otherQueueName param.
 * The reported address memory used in the console is now 60% higher
 ** In my example the reported size was 256.43MB

 

I have a Red Hat ticket ([https://access.redhat.com/support/cases/#/case/03076511]) about this and it was suggested that I should create Jira ticket to discuss it further with developers. It was mentioned that management calls themselves use memory and that this could be causing the issue, but I don't see why management calls would use address memory.
