 Replying to [comment:1 westonruter]:
 > @bstovall does the RSS widget appear on the 404 template? If so, then
 this could result in infinite recursive HTTP requests and cause the 100%
 CPU usage you're describing.

 Sorry, totally forgot about this.

 Although I cannot confirm for sure since the template was updated to
 remove the RSS feed (before I was brought in), the 404 page does appear to
 use the same template as the other pages, so there is no reason we could
 come up with as to why the 404 page would not have the RSS feed. In other
 words: most likely.

 That's a great suggestion.
