Xenix-Digiboard Problems

[Tom Jenkins]

HELP!  Need hints (Xenix hangs with Digiboard)

I've got a problem you may be able to help me out with.  Equipment
configuration follows.  The problem is that our Xenix system hangs
every two-three weeks for no apparent reason.  I have to manually
reboot to clean up the filesystems.  Keyboard on the host locks up 
and although our 8 dial-in lines answer the incoming call, no login 
prompt.  Everything just seems to freeze.

I can't take out the Digiboard since the system is used online and
can't be off.

This has been ongoing for more than a year, and I've changed out:
Motherboard, Digiboard, Power Supply, VGA Card, Monitor and Hard 
drive (used to have a 100M Toshiba, same thing)

I've tried different memory (high and low) combinations on the Digiboard,
with no success (I/O port 0x320, Memory Address's of F00000 and D0000)

I'm running V4.6.0 on Digiboard software and standard Xenix drivers for 
the Archive.

DTK 80386 at 25Mhz with 64K cache, 4M Ram
