We've got about 11.1 million PV entries to play with, so I went
ahead and made MaxClients 150 just to ensure Apache couldn't
panic the system at will. That combined with minimizing the
KeepAliveTimeout has solved the problem for now, though I'm still
not happy about letting all that RAM sit idle. I guess I'll just have
to live with it.
Eventually, I may be forced to turn off KeepAlive and make use of
FreeBSD's accept filters or put in a reverse proxy as you
recommend. For now, though, we are serving the whole gammut
from this Apache. Static pages, images, mod_perl, PHP,
Apache::ASP, and most anything else a customer might want or
need to serve from a web server. I know it isn't the most efficient
way to use Apache, but nobody has any complaints about
performance at this point.
