Ok. I'm sorry.

I could hardly imagine, what difference could be between SFTP servers that
could cause that problem. I sent you problem SFTP account auth data in
private letter (that I sent to daniel_at_haxx.se). Could you please try to
upload some file to that server to see what happens?

I found it while I was debugging the "curl" tool uploading file to the
problem SFTP. I was surprised that the program tried to send 0 bytes when
input stream sill contains data.
Is this problem easy to repeat for you?
Yes the problem is rather stable.
