New Post: Problem with sftp uploading

I have problem with uploading of several big files in one session into linux server.

for example:
I try to upload 17 files in loop.

3 - success, after that I waiting during 1 hour and then i get exception:


System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host

at Renci.SshNet.Sftp.SubsystemSession.WaitHandle(WaitHandle

waitHandle, TimeSpan operationTimeout)

at Renci.SshNet.SftpClient.InternalUploadFile(Stream input, String path, Flags flags, SftpUploadAsyncResult asyncResult, Action`1

uploadCallback)

I think that there is problem is in this part of code.

do

        {
            //  Cancel upload
            if (asyncResult != null && asyncResult.IsUploadCanceled)
                break;

            if (bytesRead > 0)
            {
                if (bytesRead < this.BufferSize)
                {
                    //  Replace buffer for last chunk of data
                    var data = new byte[bytesRead];
                    Buffer.BlockCopy(buffer, 0, data, 0, bytesRead);
                    buffer = data;
                }

                var writtenBytes = offset + (ulong)buffer.Length;
                this._sftpSession.RequestWrite(handle, offset, buffer, null, (s) =>
                {
                    if (s.StatusCode == StatusCodes.Ok)
                    {
                        expectedResponses--;
                        responseReceivedWaitHandle.Set();

                        //  Call callback to report number of bytes written
                        if (uploadCallback != null)
                        {
                            //  Execute callback on different thread                
                            this.ExecuteThread(() => { uploadCallback(writtenBytes); });
                        }
                    }
                });
                expectedResponses++;

                offset += (uint)bytesRead;

                bytesRead = input.Read(buffer, 0, buffer.Length);
            }
            else if (expectedResponses > 0)
            {
                //  Wait for expectedResponses to change
                this._sftpSession.WaitHandle(responseReceivedWaitHandle, this.OperationTimeout);
            }
        } while (expectedResponses > 0 || bytesRead > 0);

        this._sftpSession.RequestClose(handle);
    }

I think the variable bytesRead became = 0 but expectedResponses can't be 0...
