Don't bet on it (hotine support answers).  We are experiencing the same
KERNEL MMU FAULT (F_ACCESS) problem.  We run a 3B2/600 SVR3.2.2, TCP/IP
3.0.1.  Our system was failing sometimes DURING going to 'init 3', and 
other times at most 15 minutes after coming up.  The hotline said to do
a partial restore (non-trivial solution).  Then our system was stable
for about two weeks, now it has failed twice in the last three days.
The hotline didn't seem familiar with the problem.  DOES ANYONE OUT
THERE KNOW WHAT"S GOING ON?

------ 
... on a completely different topic:  Is anyone out there running
a similar configuration w/ smail3?  We'd like to support mail for
locally attached uucp accounts, but we do not have any out-going
uucp connections.  Thus we need uucp mail and internet mail to
talk to each other.  ANy help/advice would be greatly appreciated,
the easier it is for me to do this, the better the chance it'll
happen.
