These are some services I would normally turn off on web servers.
NOTE: usage may vary.

  1. gpm — mouse
  2. mdmonitor — monitor raid devices
  3. netfs — nfs, samba etc…
  4. autofs — automount, nfs, cd etc…
  5. kudzu — detect new hardware
  6. restorecond — monitor selinux file context
  7. mcstrans — mandatory access control selinux translation

There may be more, but if you’ve cleaned up your rpm packages, it would probably not exist.
