Thanks, Krist, William. I knew about the PHP reluctancy regarding threads, but it had worked for years, so I didn't think about it. It definitely seems like a plausible culprit. I can at least easily try the prefork version on one server, and check if I still get error messages and hangups. The fastcgi option seems to be an interesting possibility, I'll look into it as well. Thanks guys, I'm on my way of a clean prefork Apache rebuild and more testing.
