    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?
