Well, that's why I'm asking! I don't know if they are a problem or not.
Seemingly, they are all getting caught and corrected.
Of course, that makes one wonder ... in a non-ECC machine, would it be
common to have a single-bit memory error every few days? Since they
wouldn't be automatically caught or corrected, such memory errors would
probably be harmful.

No, I'm not. The logging arrangements on the Challenge, as I got it, were
pretty lame. I suppose they were the IRIX 6.5 defaults, since the OS n the
machine seemed to be a fresh install, but in any case, very little of use
was getting logged. I improved this, and got more information, and at some
point these errors showed up.
Were the errors there before, but not logged? I dunno. Were they logged,
but somewhere I didn't see? Beats me.

I guess that's sorta what I was asking ... "Is this normal?"
