We are running USG 5.0 on a Vax 11/780 with 4Mbytes of memory.
Our system is taken down automatically for backup at 5:00 am
every morning and brought back to multi-user at ~5:50 am. Here
are the first three lines from a 'ps -ef' taken at 2:45 pm:
UID PID PPID C STIME TTY TIME COMMAND
root 0 0 0 Sep 27 ? 2140:46 swapper
root 1 0 0 Sep 27 ? 34:29 /etc/init
root 0 0 0 Sep 27 ? 0:00 swapper
We average about 20 users at any given time in the day -- never over
25 users. Most of them are using emacs or doing very small stuff --
the only hogs that are running are vc (a visual calculator), nroff,
and a fair amount of uucp activity. Not NEARLY enough to justify
any swapping at *ALL*, much less what I seem to see above.
What am I missing, or what might be the cause of this and how
can I remedy it? Please reply via mail to keep net.unix-wizards
congestion to a minimum.
Thanks for your time,

Curtis,
Check the way the system is incrementing u.u_stime in clock.c. It
may be that USG 5 doesn't disriminate between kernel mode activity and
idling (pc == waitloc, where waitloc is a location in idle()). If you want
actual activity noted, it should only increment u.u_stime when pc != waitloc.
