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

             Summary: Message redistribution does not work when using message grouping
                 Key: ARTEMIS-3265
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3265
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 2.17.0
         Environment: {noformat}
*no* further _formatting_ is done here{noformat}
            Reporter: Luc IMBERT
         Attachments: broker.xml, broker.xml, test-producer.tar.gz

I have set up a two nodes Artemis broker on my laptop computer. I have set up message grouping and message redistribution.

The two broker.xml files are joined to ticket, as well as the Spring Boot application I am using to inject messages with groups.

I use two instances of the regular artemis consumer to consume the messages on each brokers. 
Here are the commands I am using :

To launch consumer on the first broker : 
 
{noformat}
[user@hostname]tmp$ cd broker1/
[user@hostname]broker1$ ./bin/artemis  consumer  --verbose  --message-count 100000 --user admin --password XXXX
{noformat}

on the second broker : 

{noformat}
[user@hostname]tmp$ cd broker2/
[user@hostname]broker2$ ./bin/artemis  consumer  --verbose  --message-count 100000 --user admin --password XXXX
{noformat}
 
And to inject message on the first broker (127.0.0.1:61616)

{noformat}
[user@hostname]tmp$ cd test-producer/
[user@hostname]test-producer$ mvn test
{noformat}

If I halt one of the consumers, say on broker1, while it is receiving message, all messages of the group it already has handled get stuck on the broker.

Admittedly asking for redistribution is somewhat contradictory with the group concept, but is there a way to change this behavior ?
