Information processing apparatus having memory dump function, memory dump method, and recording medium

摘要

An information processing apparatus that executes an operating system, the apparatus including a panic process unit configured to stop the operating system when the operating system has detected an error, a mapping process unit configured to assign, to the operating system stopped by the panic process unit, a second memory area which is other than a first memory area being used by a kernel of the operating system before stop or by a hypervisor that controls the operating system before stop of the operating system, a reactivation process unit configured to reactivate the operating system by using the second memory area as a usage area, and a memory dump process unit configured to read data in the first memory area, and to write the data to a dump file after the operating system is reactivated.
