Programação Java

int porta;
int numClientes;

porta = Integer.parseInt(textPorta.getText());
			
numClientes = Integer.parseInt(textNumClientes.getText());
			
         try{
          ServerSocket servidor = new ServerSocket(porta,numClientes);
catch(Exception ex){
            ex.printStackTrace();
}
         }

da o seguinte erro:

A porta já está sendo usada, veja se não tem alguma coisa usando ela ou se você não executou esse programa seu 2 vezes…

Seguinte, agora quando eu mando iniciar o servidor trava o programa…

O que pode ser ??? Eu uso firewall aqui, será q é isso ?
