IdeaBlade DevForce 3.6.2.2 バージョンを使用している場合。これをトラブルシューティングする方法や、何が起こっているのかについての提案はありますか?

上記は非常に頻繁に発生するようで、システムが停止します。入力コミュニティに感謝します

PM.RollbackCheckpoint を呼び出し、PersistenceManager が現在チェックポイントしていない場合、InvalidOperationException がスローされます。PM.IsCheckpointing フラグをチェックして、PM がチェックポインティングであると認識しているかどうかを確認できます。そうあるべきだと思われる場合は、コードと PM が同期していない理由を特定してみてください: ロールバックしすぎていませんか? 以前にチェックポイントをクリアしましたか? 以前に保存して、新しいチェックポイントを開始していませんか? PM を誤って非スレッドセーフな方法で使用していませんか?

保存中のクエリのタイムアウトは少し奇妙です。DevForce は保存後に再フェッチを行いますが、スタック トレースがなければ、それが問題であることは明らかではありません。IPersistenceServerSaving または IPersistenceServerSaved を実装している場合は、そこでクエリを実行しているかどうかを確認してください。
