Subject [jira] Resolved: (AMQ-2440) stomp+nio leaking file descriptor on client drop
Date Wed, 10 Mar 2010 12:51:44 GMT

     [ https://issues.apache.org/activemq/browse/AMQ-2440?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dejan Bosanac resolved AMQ-2440.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 5.4.0

This is now fixed on trunk and 5.3 branch. It's tested manually using StompLoadTest in activemq-systest
subproject, which opens/closes a connection for every send/receive and simulates a real load
on the broker. This test should be converted to the real system test, but that's the case
for another issue.

> The bug is observed on code checkout from https://svn.apache.org/repos/asf/activemq/tags/activemq-5.3.0
> A server is initiated with stomp+nio transport on port 61612.
> A client connects. A SelectorWorker is created on SelectorManager:68.
> If the client drops the connection an exception is received at StompNIOTransport:91.
> "java.io.IOException: An existing connection was forcibly closed by the remote host".
> But selector are not cleaned up. It works with stomp transport. But not with stomp+nio.
> What I see in the end is an increasing number of "connections" if the JVM.
