私はCentOS Linuxバージョン7.4.1708（コア）を実行しているHP DL360 G7を持っています。私は以下をガイドとして使ってクラッシュダンプを調べました。https://www.slideshare.net/PaulVNovarese/linux-crash-dump-capture-and-analyticそしてhttps://www.dedoimedo.com/computers/crash-analyze.html
しかし、私が見ると、クラッシュダンプが毎回異なる原因を指しているようです。つまり、私はクラッシュダンプがどのように関係しているかを判断するためにクラッシュダンプを理解する準備ができていません。
私が得たすべてのクラッシュダンプ。競合コマンドsys、bt、および各ダンプを含むログを貼り付けます。
編集する
提案された編集のおかげで、コマンドとsys出力を貼り付けました。出力が大きすぎてここに入れることができないので、Pastebinリンクを維持しましょう。btcrashlogcrash
また、サーバーがECCメモリを実行しており、ログにMCEマークがないため、これはメモリエラーの状況だとは思わないと付け加えました。
この問題を解決する方法に関するヘルプやガイドラインをお寄せいただきありがとうございます。
