    Description

      When connect AMQ broker using the Fusesource MQTT 1.14 client. If we have a misbehaving client, such as the connection was not closed, then the connections can not be cleared by the broker.

      <connection-ttl-override>30000</connection-ttl-override>
<connection-ttl-check-interval>1000</connection-ttl-check-interval>
......
<acceptor name="artemis">tcp://0.0.0.0:52201?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=CORE,AMQP,STOMP,HORNETQ,MQTT,OPENWIRE;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;connectionsAllowed=1</acceptor>

      When the misbehaving mqtt client conenct to the broker, then other connections can not connection to the broker untill restart the acceptor.
      In addition, using <connection-ttl-override> and <connection-ttl-check-interval> the connection is still not clear.

          Bug - A problem that impairs or prevents the functions of the product. ENTMQBR-2878 AMQ broker does not clean the connection(MQTT) when the connection is broken

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
