Thanks for the response. 
I will switch to a new disk today. What i have been
doing is saving/making a full system backup to a scsi
disk (sda1).
Then when the main disk fails, I simply restore from
sda1. It has worked so well in the past, only this
time I cant restore the same saved filesets (/, /usr)
cause the system locks up before I finish the restore
process.

If I dont perform any tar process, the system works OK
for number of days, as Memory used keeps climbing.
When Mem used==Mem Avail, the system locks up again,
until a reboot. 
PS and top both have not been able to show me what is
eating up all the memory. Mind u, this box has 2GB
worth of it, and it is doing nothing more than being a
NFS server!!
I will update of performance after disk switch, but if
there anymore hints, they are welcomed (B4 i throw it
out-tha-window!!)

_Thanks ALL, and esp. "civilme"!
