We are currently hitting 45000-55000 queries every five minute this is usually when cpu hovers around the 6-10 percent area. This is usually from 8 am to 11:30 then it goes to around 1-3 percent in the late afternoons. I have all the services shutdown except Bind and ssh is turned off as well. I am not limiting memory to bind. As far as swapping bind doesn't appear to be swapping although I do have 2.5 meg being swapped somewhere but I don't believe it is bind but it's been there for awhile. I may look into mrtg that would be interesting to see what exacly the name server is doing.
