こんにちは、
フォーラムの CDN を無効化した後、rake posts:rebake を実行しました。
数万件のリベイク後に失敗しました。
エラーメッセージの 1 つ（“PQsocket() can’t get socket descriptor”）を検索すると、Rake:rebake crashes with errors: PG::ConnectionBad: PQsocket - #8 by j127 というページが見つかり、そこでスワップ領域を追加することで問題が解決したとありました。
しかし、今回の問題が同じものかどうかは確信が持てませんが、試してみたところ、リベイクは依然として失敗しています。スワップを追加した後は、以前よりも多くのリベイク後に失敗する可能性はありますが、最初の失敗時に何件リベイクしたかは記録していませんでした。
発生している現象：
- リベイクが開始され、160 万件の投稿のうち約 20 万件でクラッシュします。

リベイク中の free -h の出力は以下の通りです（リベイク中は値がほぼ一定でした）：
total used free shared buff/cache available
Mem: 7.6Gi 4.6Gi 231Mi 2.1Gi 2.8Gi 709Mi
Swap: 2.0Gi 1.8Gi 194Mi
また、ディスク容量も十分に残っています（最初は足りませんでしたが、念のため空き容量を増やしましたが、状況は変わりませんでした）。
このフォーラムでは過去数年間に何度か全投稿のリベイクを行いましたが、これまで問題に直面したことはありませんでした。フォーラムの規模も大きく成長しておらず、サーバーの仕様も以前と同じです。
