For what it's worth, I've taken the additional step of running `lsof |grep
httpd > http.dump` and posting it online. My understanding is that this
shows all of the httpd open files that are adding up to my high totals.

If anyone who understands this better than me has a minute, I'd appreciate
whether you could say whether something is out of the ordinary.
The first thing that comes to mind, is that you probably want to use some of the lsof filtering options, so that your list really shows only open files on the filesystem. I have the impression that quite a lot of the stuff shown are not really open files, and may not really count against a ulimit.
But then again, my knowledge of lsof is quite limited.
The second thing I notice, is that you seem to have just about everything under the sun running under your Apache, so I'm not so surprised that you would have a lot of files open.
I see things there that make me believe you have stuff running under Apache like, at least : python, ldap, sql, kerberos, imaging stuff, geos, fortran, xml parsing, and whatnot.
As good as Apache is, I am sure there is a limit somewhere as to what one poor server can take as abuse.
You might want to look around your "LoadModule" directives, and check what you really need.
