[jira] [Commented] (DIRMINA-1076) Leaking
NioProcessors/NioSocketConnectors hanging in call to dispose
[ https://issues.apache.org/jira/browse/DIRMINA-1076?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16358449#comment-16358449 ]
Jonathan Valliere commented on DIRMINA-1076:
--------------------------------------------
Okay, thank you. I would like to have all the necessary information in one place. Please attach the patch, the logs, and enough instructions that I can follow to setup and reproduce the issue.
I also need the following: OS version, JVM version, JVM Options used for the test, Processor Model(s) of your Target(s) computer; Versions of Mina which are failing and Git locations
Basically everything you can think of that could be different from your environment than mine.

> Key: DIRMINA-1076
> URL: https://issues.apache.org/jira/browse/DIRMINA-1076
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.0.16
> Reporter: Christoph John
> Priority: Major
> Attachments: mina-dispose-hang.txt, mina-test-patch.txt
>
>
> 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?
