Abstract
A method and apparatus of the present invention includes a network access server (NAS) for use in a communications system utilized by users of telephone, fax, or modem calls, the NAS having more than one processor with a plurality of processors forming a module, each processor for performing various functions by executing code stored in a memory device accessible by the processor wherein either upgrading of the stored code or recovery of one or more of the processors is required. The NAS determines that one or more of the processors of a particular module is 'bad', marks the bad processors as being in a 'Recovery Pending' state, schedules recovery of the ‘bad’ processor during a window of time defined by a predetermined duration of time in the day during which the communications system is least utilized by the users, disables the particular module so that no calls are processed through the particular module, attempts recovery of the ‘bad’ processor during the window of time and if the step of attempting recovery takes longer than the window of time, stops the recovery and retries recovery during the window of time on the next day.
