It sure would be nice to have some better tools to find out what caused that kind of thing. It's rare (a little less than every six weeks or so), but annoying when it happens. I don't see anything unusually in terms of disk or memory use, and those session and traffic counts aren't all that high for our site, either. It's too brief to find anything in the moment, and too debilitating to get meaningful reports if it lasts longer.
