Stuck on CLOSE_WAIT

Question

I opened a socket between two machines (Linux-Linux).
The problem is when one of the sides close its socket the socket hangs on the other side (CLOSE_WAIT) till it closes it explicitly.
When I run the same thing on Windows machine the socket close on both machines.
Is there any way to work atound this?
Thanks,
Guy

Try running this server and client. What happens?
You really, really, really need to close your sockets.
import java.net.*;
import java.io.*;
public class Accept
    public static void main(String[] args)
     throws Exception
        ServerSocket serverSocket = null;
     java.util.LinkedList sockets = new java.util.LinkedList();
        try {
            serverSocket = new ServerSocket(6666);
        } catch (IOException e) {
            System.err.println("could not listen on port 6666: " + e);
            System.exit(1);
        while (true) {
         Socket socket;
         try {
          socket = serverSocket.accept();
         } catch (IOException e) {
          System.err.println("accept failed: " + e);
          Thread.sleep(1000); // Avoid buzz loop
          continue;
         sockets.add(socket);
         System.out.println("accepted " + sockets.size() + " clients");
import java.net.*;
import java.io.*;
public class Connect
    public static void main(String args[])
     throws Exception
     while (true) {
         Socket socket = new Socket("localhost", 6666);
         socket.close();
}
