title: Why does my python script randomly get killed?
body: <p>Basically, i have a list of 30,000 URLs.
  The script goes through the URLs and downloads them (with a 3 second delay in between).
  And then it stores the HTML in a database.</p>
  
  <p>And it loops and loops...</p>
  
  <p>Why does it randomly get "Killed."? I didn't touch anything.</p>
  
  <p>Edit: this happens on 3 of my linux machines. 
  The machines are on a Rackspace cloud with 256 MB memory.  Nothing else is running.</p>
