No I did not ;) Thank you very much for pointing this.

> 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: tontonflingueur005
> Priority: Major
> 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 ?
