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 un
    usable state for an indeterminate amount of time. See also scratch monkey
