No, it doesn't. Open up your copy of the OS/2 Debugging Handbook and
search for:

exception code

You are confusing exception codes with Intel trap codes. They are not the
same.

To save you the stress of locating and, perhaps, installing the Handbook:

0C0000005H
XCPT_ACCESS_VIOLATION

This relates to Traps 0x09, 0x0b, 0x0c, 0x0d and 0x0e.

P1 Access Code

00000000H XCPT_UNKNOWN_ACCESS
00000001H XCPT_READ_ACCESS
00000002H XCPT_WRITE_ACCESS
00000004H XCPT_EXECUTE_ACCESS
00000008H XCPT_SPACE_ACCESS
00000010H XCPT_LIMIT_ACCESS

FaultAddr
XCPT_READ_ACCESS/XCPT_WRITE_ACCESS
Selector XCPT_SPACE_ACCESS

They are tough to isolate. What I do is maintain a boot log. This is
pretty much automated. A command in startup.cmd writes a timestamp record
to the log file and an object in the startup folder opens the log file in
EPM and positions it to the last line. All I have to do is note what I
was doing that required the reboot. After a while, any non-obvious
patterns will reveal themselves.

Now that you know what c0000005 means, it should be clear that any piece
of code can.

Perhaps. Are these local or network copy's? I would suspect disk
controller or NIC respectively.

Yep. IBM knows how to do this stuff. What amuses me is the number of
folks that recommend turning off and/or disabling all the failure analysis
tools. Seems to me, it would be better to spend a little time to
understand what's there and make use of it. But, that's just me.

I would. It just indicates that the log itself got corrupted somewhere
along the way. It's similar to what happens with the Netscape cache, from
time to time.
