Thanks for the suggestion. However, I'm not sure how that would be different from my example below...
In my example, I create only 1 Stub, then use it 5000 times. That is the case that causes the exception to be thrown. This should be equivalent to creating a pool of size N and each thread doing work 5000/N times. In that case, I would actually hit the exception even sooner (chronologically), as theoretically some of those threads would be working in parallel. What seems to happen is that, after a HTTP session is opened, Axis / HTTP Commons cannot possibly know that I am done with the socket. HTTP 1.1 even mandates that the socket do Keep-Alive to reduce load. Somehow, I need to tell Axis / HTTP Commons that I am done with a particular Stub / Socket and to close it. Again, thanks for the help, and I hope you or someone else has more insight. -Jake Walker, Jeff wrote: > Just a dumb idea, > but in such a high performance environment, wouldn't a thread pool work > better?, where each thread has a Stub and when it has done its work for > that open request it is returned to the pool. > If you initialize the pool to about 700 threads, then at least you have > some control over the situation (varying the pool size to accommodate > your available memory etc.) and you should never see the BindException > because any Stub blocked waiting on a timeout (or general io wait) will > not be returned to the pool yet. > > The idea needs further work.
