Dunno, but I suspect not.

You really need to see what's happening on the server side (normally I'd 
suggest running the server in debug mode, but since it's intermittent 
you would probably need to bump up the LogLevel and grep out the 
relevant session from the log).

Does the problem occur with a vanilla OpenSSH built from the source on  I'm pretty sure FreeBSD make a number of changes but I 
don't know what they are.  They should be the first point of call for 
problems with the binaries they supply.

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
