Chuck Rolke created DISPATCH-987:
------------------------------------
Summary: With policy enabled connections are not closed properly
Key: DISPATCH-987
URL: https://issues.apache.org/jira/browse/DISPATCH-987
Project: Qpid Dispatch
Issue Type: Bug
Components: Container, Policy Engine
Affects Versions: 1.0.1, 1.1.0
Reporter: Chuck Rolke
Running a connection torture test that repeatedly opens a connection as far as
sending an AMQP Open performative and then closing the connection cleanly
results in the router only half-closing the TCP connection.
A network trace with no policy. Note that the router acks the client FIN at the
end.

Config for the router and a permissive policy are attached.
