<p>PURPOSE: An information processing device, a control method thereof, and a computer-readable recording medium including a control program are provided to suppress an influence range of an error when the malfunction of data transmission occurs between nodes. CONSTITUTION: A malfunction detecting unit (37c) detects malfunction from a node included in a data transmission route. An error information generating unit generates error information based on the malfunction and generates an interrupt on a processor in the node. A processor (30) executes recovery processing based on the error information according to the interrupt. The malfunction detecting unit includes a pointer pointing information indicating a demand for data transmission, a timer measuring time after the demand, and a detecting unit detecting the malfunction of data transmission.
