I do not think that's the case. I have another box that works as a mail relay server that passes messages for exim under FBSD. Now when the freeze occurs, I check the relay server and it cannot connect to the FBSD box (both are on the same lan). That's why I think it is a general box freeze and not just a tty problem.
