OE 6.0.2 All In One can't backup and restore database

I call the OpenERP server(6.0.2 all in one for windows) using xmlrpc.
But, I got the socket error.

Type "help", "copyright", "credits" or "license" for more information.
>>> import xmlrpclib
>>> sock = xmlrpclib.ServerProxy('http://10.1.20.8:60021/xmlrpc/db')
>>> sock.dump('admin', 't_6002')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "d:\Program Files\Python25\lib\xmlrpclib.py", line 1147, in __call__
    return self.__send(self.__name, args)
  File "d:\Program Files\Python25\lib\xmlrpclib.py", line 1437, in __request
    verbose=self.__verbose
  File "d:\Program Files\Python25\lib\xmlrpclib.py", line 1201, in request
    return self._parse_response(h.getfile(), sock)

se
    response = sock.recv(1024)
socket.error: (10054, 'Connection reset by peer')

What's happened?
the 5.0.9 version is OK.

I think maybe the threading problem(6.0.2 changes)..
