A system and method for detecting a loss of a message transmitted between first and second address spaces of a computer system. The system includes a first sequence number adding part adding a first sequence number to a transmission message transmitted from the first address space to the second address space, a reception message loss detecting part detecting a loss of a reception message received from the second address space, using a second sequence number added to the reception message, and a reception sequence number notifying part notifying the second sequence number added to the reception message to the second address space as a response message. The system also includes a second sequence number adding part adding the second sequence number to the reception message transmitted from the second address space to the first address space, a sequence number management part including a non-volatile memory storing the first and second sequence numbers, a sequence number resetting part reading the first and second sequence numbers from the non-volatile memory when the second address space is destroyed and recreated, a first message loss detecting part detecting a loss of the transmission message transmitted from the first address space using the first sequence number added to the transmission message, and a second message loss detecting part for detecting a loss of the reception message transmitted from the second address space.
