Are you trying to explain how it's possible for some of the consoles to freeze but others not while talking to the same sleeping computer? If so, I did not understand your explanation.
I believe socket writes don't block until you've filled the internal socket buffer, so it's likely that the unaffected machines simply hadn't done this yet.
ah, there's the missing piece of information. Now I got it, thanks.
It's just a hypothesis. Obviously I don't have enough information to know for sure.
