[comp.unix.wizards] Trap types

voorst@wybbs.mi.org (Dale Van Voorst) (06/02/90)

I am running SCO Xenix 2.3.2 on a 286 box and I've been receiving
the following message every few days.

Trap 000D in system
ax=0040 bx=F9C6 cx=0000 dx=0110 si=0018 di=03D4
bp=0392 fl=0286 uds=0018 es=0110
pc=0060:3B93 ksp=0378
prtrap: PANIC: general protection trap

The register dump varies somewhat each time.  SCO support simply says it's
a hardware problem.  What I would like to know is what exactly do the different
trap types mean.  If anyone has a list of the trap types and what they mean
it would be very helpful.  Any additional input on this particular error
message would also be appreciated.

Thanks.

This is the result of a wild pointer reference in the kernel.  I've seen this
when the swap area gets trashed.  If kernel memory got trashed, it might do the
same thing.

Make sure that the programs you are running as root aren't trashing memory
or disk.
