I agree, it sounds notoriously like faulty RAM, which often shows its
symptoms at high load (don't ask me why).

I find that re-seating the RAM may help, at least for a short period
(expect that it might return).

You can try memtest, but apparently it gets harder and harder to detect
memory problems as new techniques are developed by hardware
manufacturers to make memory faster.

I suggest a trial and error - swap the RAM with one of the other
machines, or with a fresh set of RAM if you can get some - if the
symptoms follow the RAM from server to server then you know what the
problem is :)

HTH,
