An information processing device includes a detection unit and an avoidance unit. The detection unit monitors one or both of a utilization rate of memory capacity allocated to a process, and a processing time to take to process a request. The detection unit detects a state where a fault is likely to occur in the information processing device, based on the monitoring result. The avoidance unit executes fault avoidance processing when the state where the fault is likely to occur is detected. The fault avoidance processing is processing that lowers an upper limit number of threads from a standard value to a limit value that is less than the standard value, and extends a waiting time of a thread from a standard time to an extended time that is longer than the standard time.
