title: Existing connection close when new TCP connections are made
body: <p>I have a TCP listener service to which the clients connect. Lately I have started receiving this error related to disconnection. I connect around 20 clients to it and the connection works fine. But when I connect another 10 clients to the service, the previous connections break with a 10053 or 10054 error.</p>
  
  <p>Previously it used to run with 100 clients but I am not sure what could be the problem. The service and the clients both are running on Windows Server 2003 because I found that Windows XP has a known problem with multiple TCP connections (related to 10053).</p>
