provocative maintenance
n.
[common ironic mutation of preventive maintenance] Actions performed
upon a machine at regularly scheduled intervals to ensure that the
system remains in a usable state. So called because it is all too
often performed by a {field servoid} who doesn't know what he is
doing; such `maintenance' often induces problems, or otherwise results
in the machine's remaining in an unusable state for an indeterminate
amount of time. See also {scratch monkey}.
