Considering the high demand for consumer's purchasing 'their' products, a
mishap like "My server can't run at high cpu due to it crashing" is part
and parcel to shooting yourself in the foot as a manufactuer.

If you buy a MB/PROC that cooks just by operating as a server, which in
most cases what FreeBSD will be used for, and you know that it 'may'
crash or lockup due to heat, don't use FreeBSD.

- or -

Buy hardware that won't cook out. 

R.

PS

Have you both tried to run 4.#-[CURRENT/STABLE/RELEASE] to see if the
problem goes away?
