Trustin Lee resolved DIRMINA-584.
---------------------------------
Resolution: Fixed
Assignee: Trustin Lee
I kept the descriptor property final. Instead, I changed
AprIoProcessor.destroy(AprSession) to return immediately when no session with
the descriptor ID is found. Please confirm if my fix works for you.

> Key: DIRMINA-584
> URL: https://issues.apache.org/jira/browse/DIRMINA-584
> Project: MINA
> Issue Type: Bug
> Components: Transport
> Affects Versions: 2.0.0-M1
> Environment: Linux jellikit 2.6.24-16-generic #1 SMP Thu Apr 10
> 13:23:42 UTC 2008 i686 GNU/Linux
> java version "1.6.0_06"
> Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
> Java HotSpot(TM) Server VM (build 10.0-b22, mixed mode)
> tomcat-native-1.1.13
> apr-1.2.11
> Reporter: Geoff Cadien

> To reproduce you can simply run the EchoServer from mina-example and use
> AprIoAcceptor instead of NioAcceptor. I used the EchoClient from Julien
> Vermillard's sandbox here:
> https://svn.apache.org/repos/asf/mina/sandbox/jvermillard/ and used 20 or 30
> concurrent connections.
> AprIoProcessor.destroy() is called multiple times when an exception is
> generated in AbstractPollingIoProcessor (RST, etc.) and either epoll or apr
> doesn't like to remove a closed fd from the pollset. I believe that destroy
> is called twice because AprIoProcessor.state() returns SessionState.OPEN when
> the native fd is > 0. I don't believe once open it will ever be 0 again.
> I was able to fix the problem by explicitly settion AprSession.descriptor to
> 0 after the socket was closed although I'm not sure this is the correct
> solution.
