Please HELP.
I have been struggling for a couple of days to get an Apache web server up
and running. The server has 256MB of RAM running 3.0 RELEASE. I
continually get the message "Too many open files: unable to open a file
descriptor" I understand what the error means and I have changed maxfiles
and maxfilesperproc up and down and all around. It would seem that I am
unable to affect any change upon the files setting. I also know the number
of files that apache is trying to open and tried several times setting
both kernel parameters well above the number of files needed. It seems to
die after opening around 2700 files--no matter what I have maxfiles set
to.
During the start of apache I ran vmstat -m in the background every 5
seconds and here is what I saw:

I watched several other indicators as well but the key does seem to be
with "files" not file descriptors. RAM usage never goes above 60MB. All
other parts of the system seem to be OK. It's just the files setting that
goes all "bizarro world" on me.
Ulimit returns "unlimited" and I have tried launching it from a different
shell as well-just in case it was some hidden limit of the shell.
Everything in login.conf is set at unlimited.
Does anyone have any idea where I should look next or what the answer
might be?
