Michele Mazzucco commented on AXIS2-2593:
-----------------------------------------
Dims,
1- Why do you need to set the timeout in options as setTimeOutInMilliSeconds?
Isn't it enough to set SO_TIMEOUT and CONNECTION_TIMEOUT?
2 - The REUSE_HTTP_CLIENT option is already set in the configuration context.
Why do you need to set it into the options as well? The ServiceClient is
created using the custom conf. context, so there should be no problems,
otherwise it does not make any sense to set specific options in two places
(that is in the conf. context and in the ServiceClient options)
3 - The AUTO_RELEASE_CONNECTION options is new (I mean introduced in 1.2),
isn't it? And what does the releaseConnection do?, ideally we want to reuse the
same connection as much as possible (that's the idea behind keep alive
connections)
4 - I didn't know about the thread pool trick. BTW, instead of using an axis2
thread pool, why don't we use the thread pool of java.util.concurrent (or
backport-utils), which is much more flexible (i.e. it allows to limit the
working queue size)
Thanks,
Michele

> 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.

> 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();
> }
