Hmm, so that partially excludes PHP.

Some of the early Apache2+PHP releases weren't stable at all, I will
agree with that, but the more recent ones have been very good. Esp.
since Apache froze their API making things somewhat easier.

I _do_ run them in production enviroments. I've seen a big performance
increase by using Apache2 there. Before deploying on production
enviroments, I go thru a lot of work to test stuff throughly, including
running Apache2 on the development and prototyping machines for at least
a month. Presently we have been using Apache2 for about 6 months in
production enviroments, and we have recently (2 weeks ago) rolled MySQL4
out to production use.

Yeah, it doesn't solve the problem, but it does stop the Apache from
taking out the entire server. It caused OOM conditions in some of my
boxes when it did that.
