Networking: problems servering multiple clients

Question

hi all
i'm writing a simple client server system, with a multithread server, in order to serve multiple clients.
the client's requests to connect to the server arrive to a port (ie 1025), and then the server, through a method returns to the client another port number, and then the comunication between them starts through the new port.
all work very fine, but i tried, with 2 computers, to start two clients at the "same time" (with a gap of few milliseconds), and my system "crashes".
i think that is a problem due to the second request that arrives while the comunication of the port from the server to the client happens.
is there a way to "queue" the requests arriving to the 1025 port of my server?
if i wasn't clear i can post some code
thanx in advance

Yes, teh code I posted does nothing more then listen for incoming conections and create a new Thread wich gets the Socket created by the accept to play with. This will happen for any incoming connection on the right port and will always be handeled the same.
As you'll see in the code i posted, there is some time between ServerSocket.accept returning a Socket and ServerSocket.accept being started again. This time shouldn't be to long to be sure the serversocket is listening for incoming connections when they arrive, so don't do to much inside the loop. If your system should handle a lot of connections simultaneously wou might have to optimise this be doing thing like having a few ClientThreads created allready to save the time of creating a new Thread. This becomes more important if you ClientThread is complex and slow to create. But when handelin less the say 25 clients you should be fine with this.
