We've had a similar problem with one of our DN3000s running 10.1.  
The problem is that the /etc/ttys file (actually `node_data/etc/ttys)
occasionally disappears.  Without this file, Init doesn't know to start
DM or any other login process, so it just exits.

The solution is to re-create the file from another node, SHUTdown (not Reset)
the problem node and reboot.

Hope this helps!
