NVP vProxy：SQL VMリストアのマウントが「HTTP 409 (Conflict)」で失敗する

SQL VMのリストアは、Data Protection Restore Client (DPRC)から実行されます。
マウント プロセスが失敗し、HTTP 409 (Conflict):

NetWorkerサーバーのflr-server.logで、同じHTTPエラーが報告されます。

DPRCは、マウント操作の完了を十分に待機していません。DPRCは、アプリケーション プログラミング インターフェイス(API)コールを送信して、vProxyがまだディスクをマウントしている間にマウント セッションを閉じ、HTTP 409競合を引き起こします。

この問題は、NetWorkerエンジニアリングに提起されました。

NetWorker 19.13.0.1でコード修正を予定しています(2025年8月27日の暫定版)

この問題は、1つのSQL VMに10個のディスク(VMDK)と多数のデータベースが含まれている環境で発生しました。すべてのMSVMAPPAGENTマウント操作がこの現象で失敗しましたが、他の小規模なSQL Serverは問題なくマウントされました。
