I also thought about using slow query log to pinpoint the problem. SELECT distinct cat_ID, cat_name FROM st_categories, st_post2cat ORDER BY category_nicename; This took me by surprise. SELECT distinct cat_ID, cat_name FROM st_categories ORDER BY category_nicename; The original query was redundant and wasteful.

Servidor WEB (Apache) Support » high traffic crashing usmagazine.com I understand now that it's not really the kind of thing that can be helped on a support forum. But I'm going to document this problem in case it's helpful. Our ISP is mediatemple.net, and I've been very happy with their support up till now. I think Zeldman gives them a shout-out in his blog. We've had indications of traffic problems before this and have asked about bumping up from a dedicated virtual server to a dedicated physical server. I'm not rebuilding the site just because my ISP won't help examine where the bottleneck really is. Last night, I was getting error code I posted above.
