I recently had some trouble with a Drupal 6 site I was updating. I wanted to create a local working copy of the site to test so I downloaded the files and backed up the database, but for some reason I couldn't get the site to run. In every browser I tried I would get "page cannot be displayed" or "host unresponsive". These messages were basically telling me that something on the site was causing it to fall over before it ever got around to producing any HTML, and so the browsers were treating it as best they could. I tried clearing the Drupal cache and disabling some modules but this didn't appear to do anything, or simply broke the site. Searching the internet for this problem yielded very few results, so I eventually had to track the problem down myself.
