---------------------------------------

             Summary: Artemis doesn’t always respond with attach/detach frames confirming the opening/closing of the links
                 Key: ARTEMIS-2113
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2113
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: AMQP
    Affects Versions: 2.6.3
         Environment: This test was done in .NET using the Amqp.Net Lite library 2.1.4 (which is the latest version).
            Reporter: Simon Chalmers


A trace of a message exchange with Artemis where this has occurred is below. The lines highlighted in yellow show opening and then closing two AMQP links, but Artemis doesn’t respond after that with its own attach/detach frames, which acknowledge the opening/closing of those links. The lines highlighted in green are heartbeat frames sent to Artemis, sent every 15 seconds, which illustrates that one minute passed without receiving the attach/detach frames from Artemis.

Note that this doesn’t always happen. Sometimes Artemis does respond, as shown by the lines highlighted in grey in the trace below.
