サーバーを完全に再起動すると、サーバーは正常に動作します。 Webサイトにアクセスしていくつかのリンクをクリックすると、apache2プロセスが作成されますが終了しません。サーバーがデフォルトでクラッシュするまで、より多くのメモリを消費します。この問題を解決する唯一の方法は、apache2サービスを再起動してすべてのプロセスを終了するか、サーバーを再起動することです。
私の試みには、デフォルトのWordPressテーマを復元し、すべてのプラグインを無効にしてからサイトを再閲覧することが含まれていましたが、それでも問題が解決しないようです。また、apache.confファイルとphp.iniファイルでいくつかの設定を試しました。
私は今混乱して問題を特定するために調査を行ったが、行き詰まった路地にぶつかった。
私の質問は、なぜapache2とmysqldがそんなに多くのメモリを占有し、それを防ぐと、私のサーバーがクラッシュするのを防ぐことができるのかということです。
以下は、Apacheがメモリを占有し、複数のapache2プロセスを生成することを示す現在実行中のプロセスのイメージです。
