That's a classic sign of faulty memory. I had the same thing when I
bought four pieces of 256M ECC RAM. I had two parts each built from
NEC and Samsung chips. Much as I have liked Samsung in the past, any
time I had any piece of the Samsung memory installed, no matter which
slot, a buildworld running while doing some heavy tar compress/decom-
press operations would cause a fatal trap. Run the NEC memory alone,
no problems. Run either or both of the Samsung pieces alone, problems.
Remove the newly-added memory and ensure that the problems goes away.
If so, try using JUST the new memory alone, either one piece at a time,
or all at once, and see whether the problem occurs only when the new
memory is used. If so, return the memory for a different make or
better quality.
