I have had systems so overloaded that I couldn't log in on an ssh session, but 
when the load cleared, there weren't any ECC errors. I still think you have a 
hardware problem, and just because it takes a high load now doesn't mean that 
it is OK. A faulty timing capacitor on the motherboard can cause all sorts of 
corruption in memory, and it will probably deteriorate over time. You need to 
methodically test the memory by running memory tests, and then moving ram and 
testing again. Or replace the hardware if it is mission critical.

You hope everybody uses it, and
you notice quickly if they don't!!!!
