SFTP - Unexpected server response

Question

I am using a trial version of edtFTPPRO. I have two files that my code converts to an array of bytes and then attempts to upload to the remote SFTP server. One file can be consistently uploaded without any problems. However, whenever I try to upload the other file, I end up with an exception "Unexpected server response".

The successful file is 376 bytes. The file that always fails is 41,309 bytes. From the error message, it's hard to tell what's going on or what to do next.

I have no problem uploading the file to the server using WS_FTP.

I enabled logging and here is what was generated
