  • Closed as program error.

Error description

  • The following series of events will
    lead to out of order message processing when the gateway is
    configured with
    in-order processing mode. The latter mode specifies that all
    messages should be
    output in exactly the same order as they have been received from
    input queue.
    
    1. Message #1 is received and being processed.
    2. Message #2 is received and being processed.
    3. Message #2 reaches back side first, acquires an instance of
    MQQM object to
    allocate back side connection and then goes dormant waiting for
    Message #1 to
    be processed.
    4. MQQM is disabled.
    5. Message #1 reaches back side, unable to allocate MQQM object
    (it is already
    disabled) and fails.
    6. At this point processing of Message #1 considered to be
    finished and Message
    #2 proceeds without checking that Message #1 has failed.
