Upload randomly fails

2016-12-06 19:50

When uploading a large amount of files, it randomly fails. Once in a while it even completes successfully.
Using .NET, the version of the WinSCPNet is 1.3.6.7136.
Im using the following code:

With mySessionOptions
      .Protocol = Protocol.Ftp
      .HostName = "vaultcracker2"
      .UserName = "XXXXX"
      .Password = "XXXXXXXXX"
   End With
   Using mySession As Session = New Session
      Dim transferOptions As New TransferOptions
      transferOptions.TransferMode = TransferMode.Automatic
      transferOptions.SpeedLimit = 2500
      transferOptions.ResumeSupport.State = TransferResumeSupportState.Smart


      ' Connect
      mySession.Open(mySessionOptions)

      'Create Remote folder
      If (mySession.FileExists(szRemoteFolder) = False) Then
         mySession.CreateDirectory(szRemoteFolder)
      End If

      ' Upload files
      transferResult = mySession.PutFiles(szSavedFolder, szRemoteFolder, False, transferOptions)
      ' Throw on any error
      transferResult.Check()
      For Each transfer In transferResult.Transfers
         Console.WriteLine("Upload of {0} succeeded", transfer.FileName)
      Next
   End Using

The message I get back is: Error transferring file 'c:\a\xxxx.txt', Copying files to remote side failed.
When I look at the server log all I see is: FAILED UPLOAD

No other information is given as to WHY it failed.

One other thing, is if I use FileZilla I don't have any issues uploading.

Please attach a full session log file showing the problem.

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Log attached. While you are looking at it I have found that I have another issue;
I am trying to set the folder permissions on upload and its not working.
Here is the code

Dim myFilePermissions As New FilePermissions
                myFilePermissions.Octal = "755"

                Dim transferOptions As New TransferOptions
                transferOptions.TransferMode = TransferMode.Automatic
                transferOptions.ResumeSupport.State = TransferResumeSupportState.Smart
                transferOptions.FilePermissions = myFilePermissions

Interestingly enough when I FTP with the same user with Filezilla I am able to change folder permissions so I don't think its a umask issue as mentioned in another post.
