The file byte count is correct. Writing files is fine. With the same client, a different server works just fine. I have been trying to pin this down, so far all I know is that the packets from the server actually contain zeros for the file contents. The troubled server kernel is 5.4.1 Has anyone encountered this or is it just me?
