Apache/mod_perl is often a culprit, well, mostly mod_perl, I think. Make

requests. If you set the number to 0, they won't die, and it'll just bog
down. Our installation used to run relatively quickly at first, but as
those processes lived on, the machine slowed to a crawl; changing this
setting fixed this gradual slowdown. Not sure if this is in the docs,
but it should be...
