Facing problems with URLConnection under high load

Question

Hi,
I have a piece of code that acts as a load balancer. Under high load scenario - 200+ different simulataneous users, it throws some errors.
Following is a snippet from that code -
               URL url = new URL(site);
               URLConnection urlconnection = url.openConnection();
               urlconnection.setDoInput(true);
               urlconnection.setDoOutput(true);
               urlconnection.setUseCaches(false);
               DataOutputStream dataoutputstream =
                         new DataOutputStream(urlconnection.getOutputStream());
               dataoutputstream.writeBytes(posServiceRequest);
               dataoutputstream.flush();
               dataoutputstream.close();
               InputStream inputstream = urlconnection.getInputStream();
               httpservletresponse.setContentType(urlconnection.getContentType());
               rewriteStreams(inputstream, httpservletresponse.getOutputStream());
               inputstream.close();
Somewhere after around 200 odd users, this piece of code throws an error - "Error writing to server", a stacktrace print shows that the error occurs at the following line -
InputStream inputstream = urlconnection.getInputStream();
Any pointers would be appreciated.
Thanks,
