recv() should only ever be able to hang in blocking mode, so if you really want it to really never hang then use non-blocking.
To figure out why it hangs, you need to understand in which situation recv() is called and the state of the TCP connection at that point. I don't think that is much related to the SSH2 protocol.
Since you can't tell us how to repeat this problem, it isn't a lot more that _we_ can do about this as I can think of.
Or what can I do to "force" it to loop the same way it does from the scp.c code with the -37
Then you make sure it never hangs, which it should never do in non-blocking mode (at least).
