I hope this is to the _RIGHT_ news group.......

I have an EISA-486/33 Hardware Platform with the following Hardware 
installed, ( as reported by hwconfig  and cleaned up for readability) :-

name=fpu vec=15 dma=- type=80387
name=serial base=0x3F8 offset=0x7 vec=04 dma=- unit=0 type=Standard nports=1

name=es base=0x4000 offset=0x vec=11 dma=7 ES-3210 InterLan
                                              = LLI/MAC = Driver = (C) 1990 =
name=tape vec=- dma=- type=S ha=0 id=2 lun=0

name=disk vec=- dma=- type=S ha=0 id=1 lun=0
name=Sdsk vec=- dma=- cyls=286 hds=64 secs=32


The adapter is an AMI FASTDISK EISA disk controller with 4 MByte RAM.
The Disk drives are both Seagate 94171-350's (ST4350N) SCSI drives.
The Thinwire Ethernet Interface Card is an Racal/Interlan EISA ES-3210 card.
The Display card is TSENG LABS ET4000 Based, running 1024X768x256 colour Mode.
I also have an Overland Data TX8 Tape interface Card installed.

Below is the software installation according to swconfig :-

My default login shell is the csh.

My .login file allows my first login to open an Open Desktop Window Inteface,
and all subsequent concurrent logins on any other of the multiscreens
results in a Sys V Command line interface Prompt. This makes life easier
when running some of my applications, which include a number of high resolution
graphics applications which require the ODT-DOS window to be zoomed when used
from the Desktop. But here is my problem :-

For about ten precent of the time, when I run either the ODT-DOS shell, or a
UNIX linked ODT-DOS application from the command line.
  ( Two examples are :- Wordperfect V5.1, Gem Artline )

When I quit the application I get the following message :-


PANIC:

PANIC: Kernel mode trap Type 0x0000000E

...etc..........

A system dump to /dev/swap then occurs, and I have to reboot and repair the
filesystems.

Could anyone PLEASE help me, as to what the probable cause or causes are, and
what are the suggested fixes, if any. It does not happen everytime I run an
ODT-DOS program.
  (Running DOS from the Open Desktop works with no problems).

 PS. I control several other SCO ODT systems running as clients only, and they
don't suffer from the same problem ( Or I don't use them enough to encounter
the problem)

Thanks in advance....
