Subject [jira] [Commented] (DIRMINA-1041) WriteFuture.await() hangs when the connection is closed remotely before await is invoked
Date Mon, 22 Aug 2016 09:25:20 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-1041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15430401#comment-15430401

Emmanuel Lecharny commented on DIRMINA-1041:
--------------------------------------------

Now, that is weird. I can have the test failing constantly on Mac OSX, but for that, I have
to run the loop 100 000 times. And strange enough, it blocks around 16350 (more or less).
On Linux, it seems to block around 1000 loops. At this point, I suspect we are reaching a
limit that is OS dependent. A {{netstat -a | wc -l}} just gives a number around 500, so we
are not facing a {{ulimit}} problem.

Diging...

> When in a high throughput scenario a TCP connection is closed remotely before one of
the `await` methods on WriteFuture is invoked, the `await` method hangs.
> We've actually been seeing this issue for quite some time in our production environment
in an application that uses Apache Camel with the camel-mina2 and camel-hl7 components. I
was finally able to reproduce the issue in a unit test (see attached).
