My experience with bad memory is that if it causes the machine to crash, 
it won't always happen while the machine is running the same process (or 
kernel thread)--so look for it crashing in a wide variety of places--and 
upon inspection of the core dump, a pointer somewhere will be pointing 
to garbage.
