My server will only handle one connection. No more. We plan to close socket
to get rid of all partial data in cases of error happened. Client
disconnected is one of the error cases.

We don't have problem in the initial connection. The only problem is on the
reconnection case. The actual error code we got is 9 not 1 (sorry about the
wrong info). 9 means "Bad file number".
