dmesg 메시지, temperature above threshold

이 메시지는 CPU 온도가 설정된 임계값을 초과했음을 나타냅니다.

이 로그 메시지는 CPU의 온도가 임계값을 초과하여 CPU 클록 속도가 제한(Throttled)되었음을 나타냅니다. 이는 시스템의 냉각이 충분하지 않거나, CPU가 과부하 상태에 있음을 의미할 수 있습니다. 온도가 정상으로 돌아오면, CPU 클록 속도도 정상화됩니다.

 

해결방안은 시스템 냉각 상태 확인 및 개선, CPU 부하 관리, 시스템 설정 조정(cpufreq, turbostat), 하드웨어 문제 점검 등이 있겠습니다.
