title: problem: Socket error [Address already in use] in python/selenium
body: <p>I have a troublesome problem <strong>socket.error error: [Errno 10048]: Address already in use. Only one usage of each socket address (protocol/IP address/port) is normally permitted</strong> during automated tests using Selenium with Python. The problem is so interesting that it runs on one machine (Linux) works correctly, but on another machine (WindowsXP) generates this error.
  I would add that the problem arose after the reinstallation of the system and set up all over again - with the previous configuration everything worked properly.
  Is there maybe something I forgot? Has anyone come up with such a problem before?</p>
  
  <p>Does anyone have an idea of ​​how to deal with this problem?</p>
  
  <p><strong>The current configuration / libraries:</strong></p>
  
  <p>python 2.7, numpy, selenium.py</p>
