I have an HP Netserver LD PRO 200MHz processor, with a single 4.2 GB SCSI "Hot
Swap" drive, and 64 MB of ecc RAM.
The same problem happens when either SCO UNIX 3.2v4.2, and SCO Open Server
5.0.4 were loaded.
Under moderate to heavy disk access, the system freezes, and the hard drive
light usually stays on.
HP has swapped out hard drives, the motherboard, the cpu board, and the power
supply.  This keeps happening.  Is there a fix for this???

Thanx

Sounds like a SCSI adaptor or termination problem to me. What options
are enabled in the adaptors BIOS?

Kill all caching in the system BIOS (both video and BIOS shadowing) and
see if it handles heavy loads (perhaps slower), but if it has no
problems this will tell you the SCSI adaptor and one or more of the
shadows are stepping on each other.

Could be bad memory - or the motherboard does not correctly support ECC?

Are you sure it's ECC ram and not just parity ram? If the MB does not
use regular parity ram with the ECC logic on the MB a parity error will
just freeze the system.
