That seems pretty excessive for the ask jeeves bot. The only time I've ever seen them do that is when they got caught up in a loop (our fault). Most of the time they plod along at about one request every 5 minutes.
As for the other robots - I've seen googlebot make requests that fast. If you can dish it up they will take it. But the bot seems smart enough to slow down if you can't serve the requests that quickly.
That is very excessive. Can you give us any more information on the pages? Are they static, or dynamic? And what % of your site did Ask spider?
Ask Jeeves spider came 'round a few sites yesterday for me, but mostly grabbed robots.txt and left. To date, even on larger sites, I haven't seen their bot do this, though I haven't watched a larger scale dynamic site when the bot struck to know that it wouldn't happen in that situation...
OK, whoops! I sticked you some logs- just ignore if you want.
I will contact them, but I do not want to run the risk of getting banned. Is that possible? I conrtacted FAST once about a robot ignoring robots.txt instructions, and they said, "OK, we will put your site into our exclusions list." Noooooo!
I did also find this robot go into a loop looking for something that it kept requesting 5 times a second for at least two minutes.... and the file is SPECIFICALLY EXCLUDED in robots.txt.
