Issues with sftpclient downloads

Sep 13, 2013 at 3:14 PM
So a little bit of background, we are trying to use sftpclient to copy a whole directory structure with all files within the directories. It works well with our small sample set of directories and small text files, but when we move on to the real tree with all files (420MB worth) it stops downloading at about 20MB worth.

This is sort of the code we are using - (I'm reconstructing from memory)
Public Sub getFiles(sServer As String, sUsername As String, sPwd As String)
        Dim rSftp As Renci.SshNet.SftpClient
        Dim strPath As String
        rSftp = New Renci.SshNet.SftpClient(sServer, sUsername, sPwd)
        If(Not System.IO.Directory.Exists(strPath)) Then
        End If
        walkSFTPDirs (rSftp.ListDirectory("./tunnel_pack/"), strPath, rSftp)
End Sub

Public Sub walkSFTPDirs (ByVal dirContent As System.Collections.Generic.IEnumerable(Of renci.SshNet.Sftp.SftpFile), byval strRootPath As String, byval rSftp As Renci.SshNet.SftpClient) 
    Dim dirItm As renci.SshNet.Sftp.SftpFile
    Dim oOutput As System.IO.FileStream

    For Each dirItm In dirContent
        If dirItm.IsDirectory = True Then
            If(Not System.IO.Directory.Exists(strRootPath &  "\\" & dirItm.Name)) Then
                System.IO.Directory.CreateDirectory(strRootPath &  "\\" & dirItm.Name)
                walkSFTPDirs(rsftp.ListDirectory(dirItm.FullName),strRootPath &  "\\" & dirItm.Name, rsftp)
            End If
            oOutput = New System.IO.FileStream(strRootPath & "\\" & dirItm.Name,System.IO.FileMode.Create)
            rSftp.DownloadFile(dirItm.FullName, oOutput)
        End If

End Sub
Thanks for any pointers you may provide.
