    Yes, you could well be right. The fix about not
    checking return values from m_copy() when receiving
    broadcast messages I think, sure seems to fit what is
    happening to me. I disconnected my three machines from
    the rest of the LAN, and tried exhausting mbuf clusters
    again. This time, it didnt hang, and no rl0 watchdog
    messages either. I am ugprading the box now and will
    try a new kernel.
