> I have configured a single Dispatch Router instance to route messages through
> a broker queue (i.e. following section 7.2.5 of the
> [docs|https://qpid.apache.org/releases/qpid-dispatch-1.2.0/user-guide/index.html#routing-messages-through-broker]).
> The application does the following:
> # Forms a sending links to the queue, sends a single message then disconnects.
> # Forms a receiving link to the same queue, receives the message without
> settling then abruptly terminates the program.
> Inspecting the protocol trace, I see that after the Dispatch Router has sent
> a {{Disposition state=modified}} for the message that was held by the
> application when it terminated, a {{Transfer}}/{{Disposition state=release}}
> loop forms between the Dispatch Router and Broker until the link credit is
> exhausted.
> Protocol trace attached to this issue demonstrates the problem.
> Dispatch Router was configured by the following commands:
> {noformat}
> qdmanage create --type org.apache.qpid.dispatch.connector host=oslo.local
> port=5672 name=artemis-broker role=route-container
> qdmanage create --type org.apache.qpid.dispatch.router.config.autoLink
> addr=queue direction=in connection=artemis-broker
> qdmanage create --type org.apache.qpid.dispatch.router.config.autoLink
> addr=queue direction=out connection=artemis-broker
> qdmanage create --type=org.apache.qpid.dispatch.router.config.address
> pattern=queue waypoint=true
> {noformat}
