私はChromiumをサービスとして継続的にアイドル状態に保つ必要があるRaspberry Pi 4（4GB RAMバージョン）にキオスクアプリケーションを構築しています。私はそれをアクティブに保ち、簡単に停止、開始、ステータスの取得などを実行できるSupervisorctlサービスを作成しました。
しかし、しばらくすると、インターフェイス全体がハングすることがわかりました。私はバックグラウンドでChromiumを実行し、フォアグラウンドで3つの端末を実行しています。
tail -fターミナルサービス実行ログ- 端末の実行
dmesg -w - 端末の実行
htop
私のPiが約3時間アイドル状態になった後、インターフェイスは期待どおりにクラッシュしました。 SSHの観点からは、Piはうまく機能し、コマンドを実行し、必要な操作をすべて実行できますが、インターフェイスの面で大きな衝突が発生します。
より多くの情報を得るために端末を開いてみると、次のような情報が出ました。
- 第1ターミナルは情報を提供しません。
- 第2ターミナルは次の情報を提供します。
