Error description

  • When the environment variable MQSI_MQTT_DONT_CLEAN_SESSION is
    set so that the MQTT Nodes connect with cleanSession=false the
    nodes should not issue an unsubscribe when the flow stops. Doing
    so prevents messages being received on reconnect if they are
    published while the flow is stopped.
