Well all the tests I ran (about 2 memory testers and 2 benchmarks) caused
the box to die - even the make installs did half the time. Now that I've
disabled SMP there are no problems, and the same tests are working

The only thing I've changed is the SMP support, and now its been running for
4 days, before it wouldn't run for 12 hours

Have you shure this problem is with FreeBSD ?

First check your memory with some software like memtest86

When I've this kind of problem, always it's because some error in RAM.
