PROBLEM TO BE SOLVED: To provide a multiprocessor system capable of analyzing collaborative motion of all processors before failure when the failure occurs, with respect to the multiprocessor system where the plurality of processors 2_1-2_n are managed by a management processor 1, and accessing to a common memory 3 is controlled by a bus control device 4. SOLUTION: The management processor 1 or the bus control device 4 provides each of the processors 2_1-1_n with time information synchronized in starting the system, and the processors 2_1-2_n respectively collect self-travel history information related to the time information. When each of the processors 2_1-2_n detects the failure, it stops the self-travel history information and notifies the other processors of the detection of failure to stop their travel history information. Each of the processors 2_1-2_n stops the collection of the self-travel history information, and stores the self-travel history information in a nonvolatile memory 13 provided besides the common memory 3.
