> When using the Ssh server and writing big amounts of data towards the client, server
can freeze waiting for window adjust msg.
> It always happens after server gets into state of delaying write while waiting for window
adjust. After the window adjust is received, write is not resumed. There is no mechanism to
resume the write for server side, but on the client side there is.
> We have a junit test case that reproduces this issue. We were able to fix it with this
patch:
