Google automated requests error

http://www.google.com/sorry/misc/ I got the following url today when I was performing some SEO research. It was the first time I have ever gotten that page but when I did some forum searching I realized that a number of other people have seen it over the past year.

I was doing a lot of computer related searches, each search was just slightly different from the last. I was doing anywhere from 10 to 20 per minute, I was just noting the top three urls before moving on the net search.
