> Key: QPID-2795
> URL: https://issues.apache.org/jira/browse/QPID-2795
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: M2.1, M3, M4, 0.5, 0.6
> Reporter: Robbie Gemmell
>
> The broker is notified that no data has been recieved from the client after the appropriate heartbeating time delay, however at this point it is unable to disconnect the client. On trunk, the relevant method has no implementation and the notifiation is discarded. On the 0.5.x-dev branch it throws an IOException which is then caught by mina and provided to exception handling callback in the broker. This handler makes the assumption that the Mina session will be closed because it is an IOException since this is the behaviour Mina stipulates for the method, however it would seem that does not apply when the exception is raised from within the sessionIdle handler, as the sessionClosed handler is never called.
> As a result of the above the broker simply sits with Mina periodically firing the idle events and them effectively getting dropped. The idle handlers should be updated to explicitly close the mina session at this point and allow the broker to disconnect the client.
