> I posted about this issue in the users mailing list...
> The consumeAndCheck() method of channel/Window.java is used to enlarge the 
> receive window of channel. While tracing a libssh2 based application with 
> tracing enabled talking to a SSHD-Core Java app, I found out it sends too 
> many of these adjustment message. It was sending one every 3 packet size 
> which is quite too much considering the default packet size of 32kb. 
> The RFC 4254 is unclear about proper handling but sending one when the 
> current window size reaches half of its maximum look common. This is what 
> OpenSSH
> I've attached a patch taken from the trunk
