[jira] [Created] (ARTEMIS-2985) MQTT should not block netty thread

Gary Tully created ARTEMIS-2985:
-----------------------------------

             Summary: MQTT should not block netty thread
                 Key: ARTEMIS-2985
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2985
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: MQTT
    Affects Versions: 2.16.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 2.17.0


If some mqtt op blocks on the address or binding manager it will block the netty threads and starve existing consumers. In the same way that openwire (ARTEMIS-2685) delegates to an ordered executor, mqtt needs to do the same.

it can leave the ping response in netty to ensure connections stay open while busy.
