  <p>Getting above exception on amazonMQ, earlier we were using activeMQ where we were setting something like </p>
  
  <pre><code>&lt;transportConnectors&gt;
          &lt;!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --&gt;
          &lt;transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&amp;amp;wireformat.maxFrameSize=104857600"/&gt;
      &lt;/transportConnectors&gt;
  </code></pre>
  
  <p>In amazonMQ we are unable to find such options and broker is throwing exception. We did checked transportConnector on amazonMQ supports :</p>
  
  <ol>
  <li>name</li>
  <li>updateClusterClients</li>
  <li>rebalanceClusterClients</li>
  <li>updateClusterClientsOnRemove</li>
  </ol>
  
  <p>Any idea how can we increase size of maximum connections?</p>
