We are using PowerTCP PowerTCP SSH and SFTP for .NET 4.10 version to sftp 80 files 3.6 GB to our internal SFTP servers. We are using Sftp classs to perform the upload. Upload is calling client.Put(localFileName, remoteFileName, CopyMode.Copy); After 20 or more files are uploaded, which is about 20 minutes after connected, Put call froze and sftp server saw things like this:
"2017-12-05 20:08:57 - sftp_XAppsDev [1248829]created /inbound/3883_SCTZ-0524_09_1189591920995.pdf - 552 - 4784058 - 22  
2017-12-05 20:08:57 - sftp_XAppsDev [1248829]quit - - 221 - - - 22",

Can somebody explains why and what triggers quit command and how to fix this issue. BY the way, sftp client optimization property block size is set to 8 and buffer size is set to 131072.

So we can know more about what might be going on, can you provide the output from the Sftp.Log event when the error occurs, by outputting LogEventArgs.ToString()?
