Summary:PROBLEM TO BE SOLVED: To detect an operation abnormality of an infinite loop or a deadlock or the like.SOLUTION: A computer system executes a first thread to execute a first API function allocated a first processing, and holds a first processing content including information indicating the first processing and information indicating a second processing for updating existence information by a value indicating that the first thread is normal in memory. The first thread performs API function hook processing for executing the first processing and the second processing by reading the first processing content. A monitoring thread determines the first thread is normal and updates the existence information by a value which does not indicate the first thread is normal when the existence information indicates the first thread is normal, and determines the first thread is not normal when the existence information does not indicate the first thread is normal.
