MVC3 Web サイトからアクセスされている WCF サービス (セキュリティなし) があります。
開発者のマシンでは問題はありませんが、TeamCity セットアップが中央バージョンをビルドし、MVC3 サイトを初めてロードして WCF サービスにアクセスするときに IIS7 にデプロイすると、サービス呼び出しは次のメッセージを返します。
System.ServiceModel.ServiceActivationException: 要求されたサービス 'http://localhost:83/ABCStaticData/StaticDataService.svc' をアクティブ化できませんでした。詳細については、サーバーの診断トレース ログを参照してください。**
すぐに同じサイトに再度アクセスすると、すべて正常に動作します。
エラーがスローされたときのサーバー スタック トラックは次のとおりです。

何が問題を引き起こしているのか、またはどこから探し始めるべきかについて、誰か考えがありますか?
更新: 最初に言及するのを忘れていましたが、しばらくサイトにアクセスせずに戻った場合、同じエラーが発生し、2 回目に再び機能します。
UPDATE2: これはイベント ログ エントリのテキストです。
WebHost failed to process a request.
