Oof, up since 2004 it'll be a like swiss cheese from a security vulnerability point of view.... More likely to be the drives than the controller I think - maybe the controller is not coping very well with various failure conditions on the drives. I would try: modprobe sg then smartctl -a /dev/sgX (if you can get smartctl installed on this box) - where X is the relevent letter for each drive. You may find one or more drives with reallocated sectors (grown defect list etc.), also check the offline-corrected ECC count etc. After that you might want to look into upgrading the firmware on the controller, or possibly replacing the entire machine with a new one (which will use considerably less electricity - the 6 month electricity and cooling cost of a server of that vintage often exceeds it's total value by several times).
