At my last place of employment, we had something similar, though not
nearly as drastic.  I was told that the cladding metal on the legs of the
memory chips was different than the metal used in the chip carriers, and
that over time oxides built up which caused random parity errors.  Even
though these chips were recommended, they may be misbehaving.  (who knows
they might even be bootleg).   As an experiment, try replacing the
(newer) memory in one of the machines, and see how it acts during the
day.  Good luck.
