Marinos,

In my experience with these things, such errors are almost invariably
hardware problems. In the case you are seeing, I'd bet on a memory
problem. The VM system in FreeBSD can really pound memory and bring
out bugs.

If you have more than one memory board, try moving them around and see
if the errors change. Try pulling one and then another to see if
things clear up when the bad board is pulled. This is how I isolated
the same problem with my new K6-3/450.

Power supplies can also cause this, but I'd bet on a flaky DIMM.
