[jira] Updated: (DIRMINA-584) Using apr-transport crashes jvm on
Linux
[ https://issues.apache.org/jira/browse/DIRMINA-584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Trustin Lee updated DIRMINA-584:
--------------------------------
Priority: Major (was: Blocker)
Affects Version/s: (was: 2.0.0-M2)
2.0.0-M1
Fix Version/s: 2.0.0-M2
This is not a blocker because you can always revert back to NIO transport. Thank you for the detailed report. Let me fix it ASAP.

> 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.
