Sorry to pepper you with so many questions... but here are some more...
What do you get when you type:
  cat /proc/sys/fs/file-max
  cat /proc/sys/kernel/threads-max

On one of my well-running RH 9 boxes, I get:

  cat /proc/sys/fs/file-max

  cat /proc/sys/kernel/threads-max

You can adjust these values by becoming root and typing in something like:
  echo 16384 > /proc/sys/fs/file-max
  echo 2048 > /proc/sys/kernel/threads-max

Note: this is not a recommendation (well it is, but it's not *my* recommendation...)

BTW: I'm guessing that you are not running either NFS or NIS (NIS is a way of sharing user information amoung a lot of unix servers)

I also guess that hda1 is your /boot and that hda3 is /

That indicates that your install is using one IDE drive. I hope your
mail traffic is not too high! 

You might want to drop the Open Relay checks for a week and see if that
makes a difference. I'm not sure, but Sendmail may be holding open the
access.db file while it does these checks.
