Chromiumがアイドル状態になると、Raspberry Pi4が応答しなくなります
Raspberry Pi 4（4GB RAM Version）で、Chromiumをサービスとして継続的にアイドル状態にする必要があるキオスクアプリケーションを構築しています。それを存続させ、機能を提供するsupervisorctlサービスを作成しました。簡単に停止、開始、ステータスの取得などを行うことができます。
しかし、しばらくすると、インターフェイス全体がフリーズすることに気づきました。 Chromiumをバックグラウンドで実行し、3つのターミナルをフォアグラウンドで実行しました。
- サービスログの
tail -fを実行している端末 dmesg -wを実行しているターミナルhtopを実行しているターミナル
Piが約3時間アイドル状態になった後、インターフェイスがフリーズしたことを確認してください。 PiはSSHの観点からは機能しており、コマンドを実行してやりたいことは何でもできましたが、インターフェイス側から深刻なクラッシュが発生しました。
詳細については、開いていた端末を見て、次のようになりました。
- ターミナル1は情報を提供しませんでした。
- ターミナル2はいくつかの情報を提供しました：

さらに、Sudo service lightdm restartを実行しようとしましたが、端末がハングし、何もしませんでした。以下のsys-logを参照してください。

これが失敗した後、私はSudo reboot nowを実行しましたが、システムは再起動しませんでした。デバイスのプラグを抜いて、再び差し込む必要がありました。
誰かが私がここで何が起こっているのか理解するのを手伝ってもらえますか？この問題の原因は何ですか？
参考までに、以下のos-releaseの出力を参照してください。
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
自動起動スクリプト/ etc/xdg/lxsession/LXDE-pi/autostartを介してchromeを実行するだけで、同様のアプリケーションを作成していました
@ chromium-browser file：///home/pi/fire.html --start-fullscreen
非常によく似た方法でクラッシュします...
私が提案できる唯一の修正は、誰かがこのバグを見つけて修正を発行し、ここに投稿するのを待つことだと思われます。コメントするのに十分な評判がないか、これをコメントするだけです。
