Right, in this situation I'd be considering three obvious
possibilities: (1) there actually was a temporary load on the machine
(either CPU or disk) at the time in question, e.g. cron job, which has
been overlooked, (2) there's an intermittent hardware fault, (3) there
was a soft error (can be caused by background radiation) that triggered
it.

Not saying that these are the only options but (2) in particular can be
a proper pain, and is suggested if it happens more than once, but only
ever on one machine (which is configured the same as another without the
symptom). The pattern of (3) is that something weird happens exactly
once, nothing you do can replicate it and nobody else reports the same
problem.
