予期しない週末の停電調査

今朝、Fedora 22を実行しているマイコンピュータがオフになっており、次のように黒い端末IIRCにフルスクリーンが白色で表示されました。

[Rebooting] ...
System halted.

電源ボタンを押したまま再起動した後、このように不要な再起動を引き起こす原因が何であるかを把握したいと思います。一部のログを見ると、日曜日は少なくとも14時まで続きます。システムに詳細情報がありますか？どのプロセスがシャットダウンを開始しましたか？カーネルパニック、スクリプト、どのユーザーなどですか？

ハードウェアの問題や自動更新についてはわかりません。数年前のデスクトップコンピュータであり、いくつかのクローンタスクも実行します。最近、Fedora 22をクリーンアップするようにアップグレードされ、これまで見事に実行されています。

を使用すると、sudo journalctl -b -1systemdが17時36分頃にシャットダウンを開始し、5分後にシャットダウンシーケンスが続くことがわかります。

また、ネットワーク管理者は接続を確認し、同じ時間に繰り返し失敗します。以下は当時の記録から抜粋した内容である。
