title: Problems with WEBrick crashing
body: <p>Here are the details upon start up</p>
  
  <p>=> Booting WEBrick<br>
  => Rails 3.0.1 application starting in development on <a href="http://0.0.0.0:3000" rel="nofollow">http://0.0.0.0:3000</a><br>
  => Call with -d to detach<br>
  => Ctrl-C to shutdown server 
  [2011-01-11 13:43:57] INFO  WEBrick 1.3.1<br>
  [2011-01-11 13:43:57] INFO  ruby 1.9.2 (2010-08-18) [i386-mingw32]<br>
  [2011-01-11 13:43:57] INFO  WEBrick::HTTPServer#start: pid=10216 port=3000  </p>
  
  <p>periodically WEBrick is crashing. The only error message is:</p>
  
  <blockquote>
    <p><strong>ActionController::RoutingError (No route matches "/thumbnails/missing.png"):</strong></p>
  </blockquote>
  
  <p>This error message occurs from time to time (I'm using paperclip), but doesn't cause a WEBrick crash each time it occurs. I've spent a little time trying to resolve the routing error - but haven't resolved it yet. I don't think that's the root cause of WEBrick crashing though, since it doesn't happen everytime. </p>
  
  <p>Any help greatly appreciated.</p>
