gaierror: (8, 'hostname nor servname provided, or not known')

[Laszlo Nagy]

  Hello,

I asked this question about a week ago, but I did not provide a 
traceback. Here is the traceback:

  File "/usr/local/lib/python2.4/xmlrpclib.py", line 1096, in __call__
    return self.__send(self.__name, args)
  File "/usr/local/lib/python2.4/xmlrpclib.py", line 1383, in __request
    verbose=self.__verbose
  File "/usr/local/lib/python2.4/xmlrpclib.py", line 1129, in request
    self.send_content(h, request_body)
  File "/usr/local/lib/python2.4/xmlrpclib.py", line 1243, in send_content
    connection.endheaders()
  File "/usr/local/lib/python2.4/httplib.py", line 798, in endheaders
    self._send_output()
  File "/usr/local/lib/python2.4/httplib.py", line 679, in _send_output
    self.send(msg)
  File "/usr/local/lib/python2.4/httplib.py", line 646, in send
    self.connect()
  File "/usr/local/lib/python2.4/httplib.py", line 1072, in connect
    sock.connect((self.host, self.port))
  File "<string>", line 1, in connect
gaierror: (8, 'hostname nor servname provided, or not known')

The program is connecting to the same host about 2 times per minute. 
After running for one or two hours, it raises this exception. Once it 
raised this exception, it keeps raising in. (My program is trying to 
connect but it cannot.) Then I restart my program and it works for 
anoter hour or two. I tried the same program on different machines and 
different operating system, but the error is always the same. Please 
help me identify the problem.

Thanks,

   Laszlo
