Server device and computer system

The present invention provides a computer system in which the results of processing performed by an application running on a slave device can be taken over when the slave device is reset after the communication between the slave device and the master device has been interrupted. A slave server constituting the computer system of the present invention is provided with an application monitoring unit which, after a watchdog timer has timed out, monitors whether processing initiated by an application prior to the time-out is completed, wherein if the processing is completed, the application monitoring unit outputs a notification signal indicating the completion, and transmits output data to another server device via a network, said output data including both the results of the completed processing performed by the application and an added identification flag which indicates that the processing has been completed after the time-out of the watchdog timer.
