Subject [jira] Commented: (QPID-2004) On shutting down the broker, the connection state of active connections is not freed
Date Wed, 02 Jun 2010 08:55:40 GMT

    [ https://issues.apache.org/jira/browse/QPID-2004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874509#action_12874509
] 

Gordon Sim commented on QPID-2004:
----------------------------------

I'm certainly happy to have an alternative solution committed in place of this.

The clusters PollerDispatch uses the disconnected callback purely to detect errors, as this
occurs on shutdown now as well I added the ability to test whether the Poller had been shutdown
and avoided treating the disconnect as an error in that case.

I should also note that the changes I committed only affect linux, so the issue remains on
windows.

> The IO layer (e.g. AsynchIOHandler for TCP) creates and holds a ConnectionCodec object
by pointer for each connection. All connection state is rooted in that object. However for
connections that are active when the broker is shutdown, those objects and all their internal
state, is not freed but is leaked.
> As the broker is shutting down anyway, the leak is not nice but not critical (henc I've
marked this as minor rather than major). However it can lead to e.g. Queue destructors not
being called etc.
