Upload error with FtpWebRequest

Question

With VST 2008 when i make upload with this code after 2.15 hours i have an error.

The FTP server send a status code 200 but the file of 23 go is always not complete about 10%.

It's always between 2.15 -2.30 h of upload.

Any solutions ?

We try some library and always the same error.

Many tests have be made in few computer with different internet providers.

 FileInfo fileInfo = new FileInfo((@psRepertoire + @psFichier).Replace(@"\\", @"\"));
                    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(this.lParams.Options.OptionsWebvox.ServeurFtp + psFichier);
                    request.Method = WebRequestMethods.Ftp.UploadFile;
                    request.Credentials = new NetworkCredential(this.lParams.Options.OptionsWebvox.UsagerFtp, this.lParams.Options.OptionsWebvox.MotPasseFtp);
                    request.UsePassive = true;
                    request.UseBinary = true;
                    request.KeepAlive = false;
                    request.ContentLength = fileInfo.Length;
                    request.Timeout = 999999999;
                    request.ReadWriteTimeout = 999999999;
                    long filesize = fileInfo.Length;
                    Application.DoEvents();
                    using (FileStream stream = File.OpenRead((@psRepertoire + @psFichier).Replace(@"\\", @"\")))
                    {
                        using (Stream uploadStream = request.GetRequestStream())
                        {
                            System.DateTime ldDateDebut = System.DateTime.Now;
                            long totalWritten = 0;
                            byte[] buffer = new byte[2048];
                            int bytesRead = 0;
                            while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0)
                            {
                                uploadStream.Write(buffer, 0, bytesRead);
                                uploadStream.Flush();
                                totalWritten += bytesRead;
                                if (this.InvokeRequired == true)
                                    this.Invoke(new MethodInvoker(delegate() { MajProgessionUpload(totalWritten, filesize, ldDateDebut); }));
                                else
                                    MajProgessionUpload(totalWritten, filesize, ldDateDebut);
                            }
                        }

Try System.NET Tracing to find reason of the error
