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.
The 10k tools page shows the number of close votes in the selected time range (the last day, the last two days, 7 days,... depending on what you selected). The question page instead shows the total number of active close votes.
Oddly, I've noticed a different bug with that list: a question that has been closed and reopened will be listed under the close votes section with some (usually high) number of close votes, but the question page shows no current close votes. This question is a good example (currently top of the most close votes list in the 7-day view).
I can only see the tools on Super User, but I've never noticed the behavior you describe.
