私はここ数日これを理解しようとしていますが、主な問題は、このエラーは本番構成でのみ発生し、開発環境では再現できないことです。
この問題は、サイトがジアゾを使用した新しいデザインでアップグレードされたときに始まりました。また、Centos5.6からCentos6に移動されましたが、それほど重要ではないと思います。それ以外の場合、bulidout.cfgは変更されませんでした。
ローカル開発マシンでエラーを再現しようとすると、インスタンスがdebug-mode = offで実行されている場合にのみトリガーでき、プロセスはバックグラウンドで実行されている必要があります。フォアグラウンドで実行されている場合は常にエラーは発生しません。トリガーされず、正しい404エラーメッセージが表示されます。基本的に、開発環境ではすべてが正常に実行されますが、コードが本番環境に移動されるとすぐに、404ページが壊れます。
