Christoph John commented on DIRMINA-1076:
-----------------------------------------
The exact version is actually Xubuntu 16.04. JDK version is 1.8.0_162-b12.
I'll have to check the cpu governor stuff next week as I don't have the
necessary rights to change this. But as it seems I am on powersave. :-/

> Leaking NioProcessors/NioSocketConnectors hanging in call to dispose
> --------------------------------------------------------------------
>
> 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-log.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?
