A self-service terminal comprises a pc core; at least one module coupled to the pc core; a control application executing on the pc core for controlling the operation of the terminal; and a management application executing on the pc core. The management application is arranged to (i) monitor state of health of the pc core, the control application, and the at least one module, (ii) detect a fault state at any of the pc core, the control application, and the at least one module, (iii) monitor the control application to ascertain if a filter criterion is satisfied, and (iv) transmit a fault signal from the terminal only if the filter criterion is not satisfied.
