Hi Matthias!
Could you send us the output of the netstat -na command (on the client
and the server) when this happens?

Hi,
I'm having problems starting a big amount of async webservice
requests via Axis2 client in short time.
The requests are all started from the same Thread and should run
parallel in only small amount.
As you can see below, I start about 1000 * 5 = 5000 requests, but
only a max of 2-5 are called parallel.
For each dataset, a few information-requests are started parallel,
but I ensure that each CallbackHandler has been finished,
before requesting the informations for the next dataset.
For the first several hundred requests this works fine, but after
some time, my network (OS is Windows 2000) goes down,
which means that the complete OS looses the connection to the local
network.
I guess this could be based in opening too much TCP connections or
something like this,
because if it affects the whole OS and not just my application, it
has to be something with the network device or driver.
So basically my question is:
Is it ensured that the TCP connection is already closed when
CallbackHandler.onError or CallbackHandler.onComplete is called?
Or must I do this myself in any way?
Do you have any other clue what might be the problem here?
Thank you!

A quick mock-overview of how I start the threads:
List<Dataset> datasets; // approx. 500 - 1000 objects
...
for (Object data: datasets) {
List<Callback> callbacks;
for (Information info: myRequestsForThisData) { // approx.
2-5 objects
// Generating the Request Document
Request request = generateRequest(info);
// Generating a service Callback instance; the Callback
class has an attribute "finished"
Callback myCallback = new Callback();
// remembering the callback
callbacks.add(myCallback);
// starting the async request
stub.startRequest(request,myCallback);
}
// now wait until all Callbacks are finished (finished is true
if onError or onComplete has been called)
while (true) {
boolean allCompleted = true;
for(Callback callback: callbacks)
if (callback.isFinished()) {
allCompleted = false;
break;
}
if (allCompleted)
break;
Thread.sleep(25);
}
}
