After full hardware examination i discovered what was behind these
unexplainable crashes.

We're using a gigabyte ga-6bxds motherboard wich supports 2 pii
processors. We acquired the machine already assembled and (strangely)
running. 

We're using only a single processor and our suplier naturally
installed it in CPU1 slot. This was the problem.

These boards require single-processor setups to use CPU2 slot, thus
the sudden freezes.

In the board booklet, this indication comes almost unnoticed. Gigabyte
should put more care in their docs.
