python socket server address already in use

Question

Hi I'm trying use python's SocketServer.TCPServer The question here doesn't give any solution and closed as unclear

My sample code

class MyTCPHandler(SocketServer.BaseRequestHandler):
    def handle(self):
        # self.request is the TCP socket connected to the client         
        self.data = self.request.recv(1024).strip()                      
        print "{} wrote:".format(self.client_address[0])                 
        print self.data                                                  
        time.sleep(5)                                                    
        # just send back the same data, but upper-cased                  
        self.request.sendall(self.data.upper())                          
        print 'done handing request from {0}'.format(self.client_address[0])

if __name__ == '__main':
    HOST = socket.gethostname()
    PORT = int(sys.argv[1])
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)
    server.serve_forever()

Problem is when restart the server it says

socket.error: [Errno 98] Address already in use

Looked at what server.shutdown() is doing in SocketServer.TCPServer.

It is not closing any socket, so I have tried running this in a different thread an handling the shutdown of the server by calling

server.shutdown()
server.server_close()

Tried changing the order of the calls to shutdown() and server_close()

I still get socket.error: [Errno 98] Address already in use

I used curl command to test.

Using netstat I can see that the port is in TIME_WAIT state
