2つのノードを持つIIS7.5Windows2008RC2ファームでwebfarmフレームワーク2.0を使用しています。一日に数回、農場は突然失敗します。基本的に2つの異なるタイプの障害があります。1つはthumbs.dbファイルがロックされているため、もう1つは「applicationHost.configが無効です」に関するものです。どちらの場合も、変更はファームにデプロイされていません。定期的な間隔でウェイクアップして差分をチェックし、突然失敗します。最初のケースでは、多くの場合、修復によって問題が修正されます。2番目の例では、2番目のノードのapplicationhost.configファイルに任意の変更を加える必要があります。これにより、再同期が強制されます。
2つのエラーメッセージは次のとおりです。

回避策は同期を無効にし、同期を実行して特定のエラーを無視する手動ワークフローを作成することであると示唆するいくつかの投稿に出くわしました。しかし、もっと良い説明があることを願っています。thumbs.dbエラーの場合、サムネイルキャッシュをオフにするだけで役立つかどうか疑問に思っていますか？
