Orchestrator の例外

Orchestrator の構成の一般的な例外とその原因 (初期化エラーやセクション認識エラーなど)。

500.30 ASP.NET Core app failed to start - ConfigurationErrorsException: Unrecognized configuration section system.web

Exception

Exception Info: System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section system.web. (C:\Program Files (x86)\UiPath\Orchestrator\UiPath.Orchestrator.dll.config line 228)

 at UiPath.Orchestrator.Startup.Program.Main(String[] args)
 at UiPath.Orchestrator.Startup.Program.<Main>(String[] args)

原因

この問題は v2021.10 へのアップグレード時に発生することがあり、原因は設定システムが初期化に失敗し、次の例外が返されることにあります。

Exception Info: System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section system.web. (C:\Program Files (x86)\UiPath\Orchestrator\UiPath.Orchestrator.dll.config line 228).

解決策

UiPath.Orchestrator.dll.config ファイルから以下の構成セクションと、対応するサブセクションを削除して修正します。

• <system.web>
• <system.webserver>
• <system.webServer>
• <system.serviceModel>
• <nwebsec>
• <system.net >

500.30 ASP.NET Core app failed to start - Managed server didn't initialize after X ms

Exception

Application '/LM/W3SVC/1/ROOT' with physical root 'C:\Program Files (x86)\UiPath\APPLICATIONNAME\' failed to load coreclr. Exception message:
Managed server didn't initialize after X ms.

原因

起動制限時間は、CPU 使用率の高さやメモリ消費量の多さに影響を受ける環境で制限がかかり、ダウンタイムが発生することがあります。

解決策

20.10.5+ にアップグレードして、起動制限時間を 300 秒に増やします。

これでも不十分な場合は、サーバーが何かを実行しようとしていて、デッドロックが発生していることを意味します。これは通常、EnableMigrations パラメーターが True に設定され、メインスレッドをハングさせる大規模な移行がある場合に発生しています。

フラグが False に設定されている場合は、メモリ ダンプを収集し、顧客の担当者に送信します。

原因

これは、番号のローカリゼーションに関連するサーバー OS の問題です。

解決策

en-US 設定の新しいイメージを使用してサーバーを再インストールします。

原因

構成ファイルの <nlog> セクションで NlogConfigurationExceptions パラメーターが true に設定されています。

解決策

設定を訂正するか、<nlog> プロパティで throwExceptions プロパティを false に設定します。
