したがって、node.js に問題があります。どういうわけか、server.js を実行していると、プロセッサがすぐに熱くなりました。それで、「top」コマンドを使用する理由を理解しようとします。リストを見ると、数秒おきに実行されるコマンド「find」があることがわかりました。そして、それは 1 つだけではありません... 10 以上で、CPU を 10% 以上使用しています。
その後、コマンド「cat /proc/"find_pid"/cmdline」を使用すると、次のようになりました: find -L/(-ipath/.git-prune-or-ipath/node_modules-prune-or-ipath/bower_components- prune-or-ipath/.sass-cache-prune)-or(-typef-and-mmin-10.316666666666666-print)
他の「find」コマンドの PID を変えて実行したところ、 -print の前の数字が変わった以外はほぼ同じ結果になりました。
これを引き起こした原因を知っている人はいますか？
なぜなら、私はここで何が起こったのか完全に盲目だからです。
nodemon を使用して server.js を実行しています。
以前はありがとう...
