I forgot what I was going to say...

Oh yeah!  Last week I started getting Very Strange Behavior on my 750
running 4.1bsd.  Ordinary programs, like "cat" and "ls", started
dumping core.  The machine crashed twice in two hours.  Suspecting
hardware, I ran diagnostics and turned up a bad memory board.

Now I don't mind things breaking occasionally.  Beaver has been pretty
good to me, compared to some other machines around here (no names).
But it disturbs me that bad memory first manifested itself in flakey
behavior, rather than in some notification from the kernel of parity
errors.  Why didn't my Unix kernel catch this problem?

I would be interested in hearing from anyone who has had memory go out
on them, and what the kernel did (or did not) tell them about the
condition of the machine.
