Java ServerSocket connecting to same socket multiple times

So, I'm not for sure what the problem is here, but I'm trying to create a simple server in Java, but whenever a client connects (I've been connecting via a localhost request from Google Chrome) the one single client connection will connect more than one time. (ie. every time I connect to my server via my browser the server prints "User connected successfully" 2-5 times.) I am not for sure how the main thread could possibly race back up to the top of the loop and connect to the same client more than once.

...
ServerSocket ss = new ServerSocket(9876);
while(true)
{
   Socket s = ss.accept();
   if(count >= queuesize || count >= numproducers)
   {
     System.out.println("Thread pool has reached it's limit. User access denied.");
     //....
     //error message sent to user here
     //....
   }
   else
   {
      System.out.println("User connected successfully");
      for(int x=0;x<numproducers;x++)
      {
         if(threads.get(position).isAvailable())
         {
             threads.get(x).start(s);
             position = (position+1) % numproducers;
             break;
         }
         position = (position+1) % numproducers;
      }
   }
}

Solution

Here is a workaround. It might help you.

Create a Set or Map containing hash code of all the connected Socket from server at below line
```
Socket s = ss.accept();
```
Now check every time whenever a new client is trying to connect, if its a same Socket then do nothing or close the socket.
