debian lenny sudden restart

[Amos Shapira]

1. Are you aware of ways to switch to a different virtual console
and/or cause the X server to restart - both possible from the
keyboard?
2. There are ways to "checkpoint" long running processes to disk so
they won't get lost on process or system crash.

I'm on the road at the moment so can't provide researched links (and
use a client which allows only top posting - sorry for that)

Cheers,

Amos
