Long time, no summary! Well fingers crossed the solution we have works.
Original message at the bottom of the mail, but the essential fix was to
replace the power supply (the machines are under maintenance, so Sun did
this for free). The engineer suggested if the problem persisted then he'd
swap the motherboard, but so far we have two trouble-free weeks.
