data exceeds window size

#21502 |

I have a customer using our component and trying to upload files to a GlobalScape EFT server, 6.1 SFTP server.

 

our component uses C# to upload the file.  It seems like small files (i.e. 1KB, 4KB, etc) upload just fine.  However, when we try uploading a 19K file, I can see we get the following out put in the SFTP trace log….and a zero byte file gets written to the SFTP site:

 

   at Xceed.SSH.Protocols.SSHTransportLayerProtocol.ReadPacket(IEnumerator`1 enumerator, Stream stream, Int32& packetLength, SSHPacket& packet, Int32& count)

   at Xceed.SSH.Core.SSHPacketIOManager.ReceivePacket()

   at Xceed.SSH.Core.SSHPacketIOManager.ReadThread()

SFtpPacketIOManager sends SSH_FXP_REMOVE

SFtpClient.Disconnect(). Channel: 1/0

SSHClientConnectionManager.Disconnect() starting. Remote: True Reason: 2/data exceeds window size

SSHClientConnectionManager.Disconnect() completed at 12/27/2013 1:34:32 PM with True result

 

Here’s what the C# code looks like:

 

  if (_sessionSend == null) _sessionSend = new SFtpSession(_clientSend);

                //using (SFtpSession session = new SFtpSession(_clientSend))

                //{

                SFtpFolder fldRoot = new SFtpFolder(_sessionSend);

                using (MemoryStream strm = new MemoryStream(message.InternalBytes))

                {

                    StreamFile destFile = new StreamFile(strm);

                    strm.Seek(0, SeekOrigin.Begin);

                    // fix folder path if there is a slash

                    if (fldRoot.FullName.EndsWith(@”\”) || fldRoot.FullName.EndsWith(@”/”))

                    {

                        if (FtpSendFolder.StartsWith(@”\”) || FtpSendFolder.StartsWith(@”/”))

                            FtpSendFolder = FtpSendFolder.Substring(1);

                    }

                    SFtpFolder upLoadFolder = new SFtpFolder(_sessionSend, FtpSendFolder);

                    if (!upLoadFolder.Exists) throw new Exception(string.Format(“The SFTP folder, ‘{0}’, you are trying to publish from does not exist because it is getting resolved to ‘{1}’. Please ensure that the folder supplied is relative to the current logged in folder which is ‘{2}'”, FtpSendFolder, upLoadFolder == null ? “Unknown” : upLoadFolder.FullName, fldRoot == null ? “Unknown” : fldRoot.FullName));

                    if (!string.IsNullOrEmpty(tempFilename))

                    {

                        destFile.Name = tempFilename;

                        destFile.CopyTo(upLoadFolder, Overwrite);

                        strm.Flush();

                        AbstractFile file1 = upLoadFolder.GetFile(filename);

                        if (file1.Exists) file1.Delete();

                        AbstractFile file2 = upLoadFolder.GetFile(tempFilename);

                        file2.Name = filename;

                    }

                    else

                    {

                        destFile.Name = filename;

                        destFile.CopyTo(upLoadFolder, Overwrite);

                        strm.Flush();

                    }               

                }

Seems like FileZilla and other utilities work just fine.  I’ve uploaded both a filezilla generated log and an Xceed sftp generated log that were generated when attempting to upload a 2.4 MB file .
