Davanum Srinivas resolved AXIS2-2593.
-------------------------------------

    Resolution: Fixed

Folks,

Original problem reported was fixed and the fix is in nightly. If the nightly does not work for you, then please open new bug with *your* testcase. and link this bug to your new bug. The comments have gotten so out of hand that i have no idea whose scenario has what problem and what version they are using etc...Sorry for the trouble of making you open a new test case.

thanks,
dims

>          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.

> 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();
> 	}
