--------------------------------------------
killing. with docker stop ...
> Automatic Client failover is not working
> ----------------------------------------
>
> Key: ARTEMIS-2589
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2589
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.10.0
> Reporter: richard krasowski
> Assignee: Clebert Suconic
> Priority: Major
>
> +*Problem*+:
> Automatic Client failover (reconnection due to server shutdown) is not
> working properly.
>
> *+Description+*:
> I created a live/backup group over server-discovery mechanisms. They both
> broadcast their connectors over udp and a multicast address. When the both
> servers (live and backup) are started, they are successfully recognized as
> live and backup.
>
> I have 2 clients both implemented in Java Spring. One client acts as the
> producer and one client acts as consumer. They are configured over a
> ActiveMQJMSConnectionFactory and over DiscoveryGroup mechanisms
> (udp://{color:#008000}231.7.7.7:{color}{color:#0000ff}9876){color}. The
> producer has a jmsTemplate and the consumer is realized as a Message driven
> bean.
> When I send 20 messages over the producer the live server acknowledges them
> and forwards them to the consumer. When I shutdown the live-server the
> consumer successfully failover to the backup server but the producer says:
> "*Backup is not active, trying original connection configuration now.*"
> And after a minute it throws an Error
> "*org.apache.activemq.artemis.core.client : AMQ214016: Failed to create netty
> connection*" with an *java.net.UnknownHostException*:
> It seems like the client receives the live/backup configuration and tries to
> reconnect to live server but after that it does not successfully failover to
> backup server.
>
> I created a github repo with a docker-compose environment. There is a
> producer, a live/backup artemis broker pair and a consumer.

>
> My goal is to send 200 messages and during the sending process I want to
> shutdown the server (activemq0) and I want to see a successful client
> failover of the producer to backup server (activemq1)
