저는 CentOS Linux 버전 7.4.1708(코어)을 실행하는 HP DL360 G7을 가지고 있으며 임의의 간격으로 그리고 (제 생각에는) 임의의 이유로 커널 패닉이 발생합니다. 나는 다음을 가이드로 사용하여 크래시 덤프를 조사했습니다.https://www.slideshare.net/PaulVNovarese/linux-crash-dump-capture-and-analytic그리고https://www.dedoimedo.com/computers/crash-analyze.html
그러나 제가 보기에는 크래시 덤프가 매번 다른 원인을 가리키는 것 같습니다. 즉, 저는 크래시 덤프가 어떤 방식으로든 관련되어 있는지 판단하기 위해 크래시 덤프를 이해할 준비가 되어 있지 않습니다.
내가 얻은 모든 크래시 덤프. 충돌 명령 sys, bt 및 각 덤프가 포함된 로그를 붙여넣습니다.
편집하다
제안된 편집 덕분에 명령 sys과 출력을 붙여넣었습니다. 출력이 너무 커서 여기에 넣을 수 없으므로 Pastebin 링크를 유지하겠습니다.btcrashlogcrash
또한 서버가 ECC 메모리를 실행 중이고 로그에 MCE 표시가 없으므로 이것이 메모리 오류 상황이라고 생각하지 않는다고 덧붙였습니다.
이 문제를 해결하는 방법에 대한 도움이나 지침을 주시면 감사하겠습니다.
