SftpPermissionDeniedException on Download when File Transfer in Progress

When attempting to download a file that is being written to on the source SFTP file server, I'm getting a SftpPermissionDeniedException. We trap for the error and retry the download after a 15 s pause. However, even after the file has been closed on the SFTP server the same exception occurs in code when downloading the file. It seems like the status of the file isn't updated or an exception isn't getting cleared in the SSH.NET code on subsequent download attempts.

SftpClient.DownloadFile(path, stream, callback)

The only way I've gotten this to work is to call Disconnect on the SftpClient and then Connect before attempting the download again.

Inizia dal punto di ingresso segnalato SftpClient.DownloadFile(path, stream, callback) e riproduci un download mentre il file remoto è in fase di scrittura, quindi riprova dopo che è stato chiuso. Traccia come viene gestita SftpPermissionDeniedException durante il retry e confronta il comportamento con la riconnessione del SftpClient. Il lavoro è completato quando un download successivo riesce senza disconnettersi e riconnettersi.
