Harsh, Okay from what I can understand, if you make ur underlying fd non blocking then it would work fine. Blocking FDs, unless and until one client is finished with its processing the other client will not be able to communicate with the server as the previous fd is blocked. The server is waiting on the 1st client to finish. When you have 3 ports and 3 clients then ofcourse it will work.
