python - SocketServer.ThreadingTCPServer - Cannot bind to address after program restart

Question

As a follow-up to cannot-bind-to-address-after-socket-program-crashes, I was receiving this error after my program was restarted:

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

In this particular case, instead of using a socket directly, the program is starting its own threaded TCP server:

httpd = SocketServer.ThreadingTCPServer(('localhost', port), CustomHandler)
httpd.serve_forever()

How can I fix this error message?

Answer 1

The above solution didn't work for me but this one did:

   SocketServer.ThreadingTCPServer.allow_reuse_address = True
   server = SocketServer.ThreadingTCPServer(("localhost", port), CustomHandler)
   server.serve_forever()
