Subject [jira] [Commented] (DIRMINA-1076) Leaking NioProcessors/NioSocketConnectors hanging in call to dispose
Date Mon, 26 Feb 2018 13:48:00 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-1076?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16376881#comment-16376881

Christoph John commented on DIRMINA-1076:
-----------------------------------------

Hi [~johnnyv], thanks for the patch. First tests looking good so far. I'll let our QuickFIX/J
test suite run overnight and see what happens, but looks very promising.
Thank you and cheers,
Chris.

>          Issue Type: Bug
>    Affects Versions: 2.0.16
>            Reporter: Christoph John
>            Assignee: Jonathan Valliere

> Follow-up to mailing list discussion.
> I was now able to reproduce the problem with a MINA test. Or let's say I did the brute-force
approach by re-running one test in an endless loop.
> I have attached a patch of AbstractIoServiceTest (against [https://github.com/apache/mina/tree/2.0])
and a stack trace. After a few loops the test is stuck. You can see a lot of threads hanging
in dispose() and the test is stuck when it tries to dispose the acceptor.
>  
> What is a little strange is that the javadoc says that connector.dispose(TRUE) should
not be called from an IoFutureListener, but in the test it is done anyway. However, changing
the parameter to FALSE does not help either.
>  
>  Is there anything that can be done to prevent this hang?
