	Hi William, 

		I must tell you, hat you posted is called a "stack
trace", and it's formatting is that of the kernel, when it dies on ya,
not a print out of a "Memory Allocation Table". It let's you know where
there is a bug in the kernel. Did it come up while you were tryign to
start a program? That's certainly what it looks like (the last four
lines, before "Mem-info etc..."). How ever, you might be able to get
the info you're looking for from twiddling with the "top" command (some
things you seem to be asking about are not a part of the top command's
default display, but I imagine it can be configured to do so). Later,
and good luck in your investigations!
