Interesting story but true:
A few years back, a client of ours had a z80 based mpm based system with
three vt100 terminals.
SOMETIME AROUND 5:00PM, EACH DAY (give or take a fews mins) the vt100
terminal on the main system blinked a little and the whols system crashed,
locking out whatever anyone was doing on the other two as well.
They were on a ups, they were on surgr suppressors, the serial cables were
clean, eiii specs, we slowd down the baud rate, still happened.
guess what: there was a postage meter (read BIG MF MAGNET) on the other
side of the wall.
5pm, just before going home, the receptionist whould 'ch-chunk' about 40
letters.

Either I'm missing data showing the crash time, or you didn't
include it. When does this crash happen? Is it during a burst
of cron-spawned activity?
It doesn't crash during a burst of cron activity, no. It doesn't occur at
exactly the same time each day, it moves around by a few minutes each
time. If you reboot manually it'll crash at the same time the next day
(ie, 24 hours after the reboot).
Here's the log of reboots during April. You see it crashed every day
between the first and the 16th. Then it didn't crash for 10 days. I
rebooted manually on the 26th at 20:19, and it started crashing every
day again.
