1. An information processing apparatus having a multitask operating system, comprising:
- a high-load continuation detecting part detecting continuation of a high-load state of a CPU;
a task switching history storing part storing a history of task switching operation; and
a trouble task candidate extracting part extracting candidates for a trouble task which causes the continuation of the high-load state of the CPU by referring to the history of the task switching operation stored by said task switching history storing part when the continuation of the high-load state of the CPU is detected by said high-load continuation detecting part.

Abstract
An information processing apparatus having a multitask operating system includes a high-load continuation detecting part detecting continuation of a high-load state of a CPU; a task switching history storing part storing a history of task switching operation; and a trouble task candidate extracting part extracting candidates for a trouble task which causes continuation of a high-load state of the CPU by referring to the history of the task switching operation stored by the task switching history storing part when the continuation of the high-load state of the CPU is detected by the high-load continuation detecting part.

10. A control method for an information processing apparatus having a multitask operating system, comprising:
-
a high-load continuation detecting step of detecting continuation of a high-load state of a CPU; a task switching history storing step of storing a history of task switching operation; and a trouble task candidate extracting step of extracting candidates for a trouble task which causes the continuation of the high-load state of the CPU by referring to the history of the task switching operation stored in said task switching history storing step when the continuation of the high-load state of the CPU is detected in said high-load continuation detecting step. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A program for causing a computer to execute control of an information processing apparatus having a multitask operating system, comprising instructions for causing the computer to execute:
-
a high-load continuation detecting step of detecting continuation of a high-load state of a CPU; a task switching history storing step of storing a history of task switching operation; and a trouble task candidate extracting step of extracting candidates for a trouble task which causes the continuation of the high-load state of the CPU by referring to the history of the task switching operation stored in said task switching history storing step when the continuation of the high-load state of the CPU is detected in said high-load continuation detecting step. - View Dependent Claims (20)
