The Most Close Votes tab in the tools page on serverfault (and maybe on other sites, can't get into the tools page on other sites) does not seem to be showing the correct values.

If you look at it currently, there is a question on there entitled 'What is better - 12x1 Gb RAM vs 3x4 Gb RAM?' which says it has 1 close vote, however if you go to the question itself it has 4 close votes.
