<p>I have a cluster of Artemis in Kubernetes with 3 group of master/slave:</p>
<pre><code>activemq-artemis-master-0                               1/1     Running
activemq-artemis-master-1                               1/1     Running
activemq-artemis-master-2                               1/1     Running
activemq-artemis-slave-0                                0/1     Running
activemq-artemis-slave-1                                0/1     Running
activemq-artemis-slave-2                                0/1     Running
</code></pre>
<p>I am using Spring boot JmsListener to consume messages sent to a wildcard queue as follow.</p>
<pre class="lang-java prettyprint-override"><code>    @Component
    @Log4j2
    public class QueueListener {
      @Autowired
      private ListenerControl listenerControl;
    
      @JmsListener(id = &quot;queueListener0&quot;, destination = &quot;QUEUE.service2.*.*.*.notification&quot;)
      public void add(String message, @Header(&quot;sentBy&quot;) String sentBy, @Header(&quot;sentFrom&quot;) String sentFrom, @Header(&quot;sentAt&quot;) Long sentAt) throws InterruptedException {
    
    
        log.info(&quot;---QUEUE[notification]:  message={}, sentBy={}, sentFrom={}, sentAt={}&quot;,
                    message, sentBy, sentFrom, sentAt);
    
        TimeUnit.MILLISECONDS.sleep(listenerControl.getDuration());
      }
    }
</code></pre>
<p>There was 20 messages sent to the queue and master-1 was the delivering node. When 5 messages has been consumed, I killed the master-1 node to simulate a crash, I saw slave-1 started running then yielded back to master-1 after Kubernetes respawn it. The listener threw a <code>JMSException</code> that the connection was lost and it tried to reconnect. Then I saw it successfully connected to master-0 (I saw the queue created and the consumer count &gt; 0). However the queue on master-0 was empty, while the same queue in master-1 still had 15 messages and no consumer attached to it. I waited for a while but the 15 messages was never delivered. I am not sure why redistribution did not kick in.</p>
<p>The attributes of the wildcard queue on master-1 is like this when it came back online after the crash (I manually replace the value of the field <strong>accessToken</strong> since it has sensitive info):</p>

<p>From another answer from Stack Overflow, I understand that my topology for high-availability is redundant and I am planning to remove the slave. However, I don't think the slave is the cause for redistribution of messages not working. Is there a config that I am missing to handle Artemis node crash?</p>
<p>Updated 1:
As Justin suggested, I tried to use a cluster of 2 nodes of Artemis without HA.</p>
<pre><code>activemq-artemis-master-0                              1/1     Running            0          27m

<p>With this setup, I still got the same result, after the the artemis node crash and comeback, the left over message was not moved to the other node.</p>
<p>Update 2
I tried to use non-wildcard queue as Justin suggested but still got the same behavior. One different I noticed is that if I use the non-wildcard queue, the consumer count is only 1 compare to 3 in the case of wildcard queue.Here is the attributes of the old queue after the crash</p>

<p>I've taken your simplified configuration with just 2 nodes using a non-wildcard queue with <code>redistribution-delay</code> of <code>0</code>, and I reproduced the behavior you're seeing on my local machine (i.e. without Kubernetes). I believe I see <em>why</em> the behavior is such, but in order to understand the current behavior you first must understand how redistribution works in the first place.</p>
<p>In a cluster every time a consumer is created the node on which the consumer is created notifies every other node in the cluster about the consumer. If other nodes in the cluster have messages in their corresponding queue but don't have any consumers then those other nodes <em>redistribute</em> their messages to the node with the consumer (assuming the <code>message-load-balancing</code> is <code>ON_DEMAND</code> and the <code>redistribution-delay</code> is &gt;= <code>0</code>).</p>
<p>In your case however, the node with the messages is actually <em>down</em> when the consumer is created on the other node so it never actually receives the notification about the consumer. Therefore, once that node restarts it doesn't know about the other consumer and does not redistribute its messages.</p>
<p>I see you've opened <a href="https://issues.apache.org/jira/browse/ARTEMIS-3321" rel="nofollow noreferrer">ARTEMIS-3321</a> to enhance the broker to deal with this situation. However, that will take time to develop and release (assuming the change is approved). My recommendation to you in the mean-time would be to configure your client reconnection which is discussed in <a href="https://activemq.apache.org/components/artemis/documentation/latest/client-reconnection.html" rel="nofollow noreferrer">the documentation</a>, e.g.:</p>
<pre><code>tcp://127.0.0.1:61616?reconnectAttempts=30
</code></pre>
<p>Given the default <code>retryInterval</code> of <code>2000</code> milliseconds that will give the broker to which the client was originally connected 1 minute to come back up before the client gives up trying to reconnect and throws an exception at which point the application can completely re-initialize its connection as it is currently doing now.</p>
<p>Since you're using Spring Boot be sure to use version 2.5.0 as it contains <a href="https://github.com/spring-projects/spring-boot/commit/99b43cb690e70afd39cc69783e1155a7a7b4e186" rel="nofollow noreferrer">this change</a> which will allow you to specify the broker URL rather than just host and port.</p>
<p>Lastly, keep in mind that shutting the node down <em>gracefully</em> will short-circuit the client's reconnect and trigger your application to re-initialize the connection, which is not what we want here. Be sure to kill the node ungracefully (e.g. using <code>kill -9 &lt;pid&gt;</code>).</p>
