What to do when ServerSocket throws IOException and keeping server running

Question

Basically I want to create a rock solid server.

while (keepRunning.get()) {
    try {
        Socket clientSocket = serverSocket.accept();

        ... spawn a n         


        

Answer 1

You can get an IOException on an accept() if the server socket is closed (by you) or you run out of resources, e.g. file handles. Either way, there is not much you can do about it. If the serverSocket is closed (you can test for this) you probably had a good reason to do this. If you run out of resources, you will either have to increase your resource limit, which requires a restart of your application, or you have a resource leak.
