-----------------------------------------
Michele,
Please wait for an hour and then pick up the build. one of my commits failed
yesterday night.
thanks,

> Key: AXIS2-2593
> URL: https://issues.apache.org/jira/browse/AXIS2-2593
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Affects Versions: 1.1.1, nightly
> Environment: Windows XP, Tomcat, Axis2 nightly build (also
> encountered in 1.1.1), JiBX 1.1.3, Microsoft Windows XP [Version 5.1.2600],
> 126 GB free disk space, 1GB RAM.
> Reporter: David Bueche
> Priority: Critical

> I am performing the following:
> - Executing a tight loop calling a singel web service
> - Using the same Stub over and over
> - Creating the Stub with a custom ConfigurationContext (see below)
> - Sending cleanup() to Stub after each message sent (although problem existed
> even before cleanup() was added)
> After approximately 4000 messages have been sent, an AxisFault is generated
> caused by the following exception (see below for full stack trace):
> java.net.BindException: Address already in use: connect
> It appears that connections from the client to Axis on Tomcat sometimes (but
> not always) remain in the TIME_WAIT state for several minutes. There are
> 1200-1500 TIME_WAIT connections open when the AxisFault is generated.
> If I step through the web service messages in a debugger, the problem does
> not appear to occur, as the system eventually releases the connections after
> a minute or two.
> Also, if I insert a System.gc() in the client code each time it sends a
> message to the web service (the commented out line of code below), the
> AxisFault does not occur. I have executed the loop over 60,000 times with
> the garbage collection included without generating an AxisFault. There were
> only 400-700 connections in the TIME_WAIT state at a given time, but
> performance slowed down to a crawl.
> Here is the code I am using to create the Stub:
> HttpConnectionManagerParams connectionManagerParams = new
> HttpConnectionManagerParams();
> connectionManagerParams.setTcpNoDelay(true);
> connectionManagerParams.setStaleCheckingEnabled(true);
>
> MultiThreadedHttpConnectionManager connectionManager = new
> MultiThreadedHttpConnectionManager();
> connectionManager.setParams(connectionManagerParams);
> HttpClient httpClient = new HttpClient(connectionManager);
>
> ConfigurationContext configurationContext =
> ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,
> null);
> configurationContext.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,
> Boolean.TRUE);
> configurationContext.setProperty(HTTPConstants.CACHED_HTTP_CLIENT,
> httpClient);
>
> stub = new MyServiceStub(configurationContext, target);
>
> boolean success = true;
> while(success) {
> success = stub.performService(records);
> stub.cleanup();
> // System.gc();
> }
