xmlrpc: hostname nor servname provided ?

[Laszlo Nagy]

I'm running a service on a machine. The service is written in Python (of 
course) and it connects to an XMLRPC server periodically.
It recreates the ServerProxy instance each time it needs to connect to 
the RPC server.

The server is created with this code:

server = xmlrpclib.ServerProxy(local.SERVER_URL,allow_none=True)   # 
local.SERVER_URL is something like 'https://myserver.com:3421'


After running for a few hours, I always get this:

2006-07-25 16:33:26,431 ERROR .main Traceback (most recent call last):

    sock.connect((self.host, self.port))
  File "<string>", line 1, in connect
gaierror: (8, 'hostname nor servname provided, or not known')

This exception does not stop my server program and it keeps trying to 
connect to the xmlrpc server, but it raises the same exception again and 
again.
However, if I restart the program then everything works. The XML RPC 
server has a static IP address and it is never restarted/reconfigured.
I cannot find the problem. Please help me.
