i've got an old server running redhat 7.2

whenever i try to run ls as any user i get a segmentation fault...
when i try to run 'ls' as root i get a seg fault
when i try to run 'vi' as root i get a seg fault
when i try to run 'umount' as root i get a seg fault

most other commands work ok...

system has been fine for years, last uptime was 78 days, before that 360 days w/ no troubles...

have booted to single user mode, same thing happens...

tried booting to single user and turning off swapspace (swapoff -a ) same thing...

trying boot floppy, but it will use the same kernel image that's in /boot (possibly corrupt??)

any ideas?
any help appreciated...
