Default Nautilus using 100% CPU

I've set up an Edubuntu (AMD64 Gutsy) server running here at school, with so
far three clients attached to it. We're having trouble, though, with nautilus
processes (of different users) eating up all the CPU on the server, slowing
things to a crawl.

Sound familiar to anyone? Up til now I've been logging in via SSH
doing "killall nautilus" but it's happening so frequently I don't think it's
an acceptable solution. If I'm not around keeping an eye on things, the
system is close to unusable.

That sounds highly unpleasant. Is there anything in the users'
.xsession-errors files which might indicate what problem nautilus is
having?

As a test, you might try turning off LOCALDEV in lts.conf to see if the
problem goes away.

Hi!I've had similar problems, but they solved when appling the gnome_watchdog-script.

this suggests that nautilus programs are being left running after logout and
are getting confused taking up lots of cpu (either that or you're killing
running users' nautilus sessions).

Could you check this by running:

ps faux | grep -B 5 "nautilus "

This should show you a bunch of 5-line groups like this one:

joannet 15748 0.0 0.0 4224 1540 ? S 11:49 0:00 | \_ /bin/bash --login -c env LTSP_CLIENT="brooks" PULSE_SERVER=tcp:87.42.170.237:4713 ESPEAKER=87.42.170.237:16001 /etc/X11/Xsession && ltspfsmounter all cleanup
joannet 15749 0.0 0.3 30068 10888 ? Sl 11:49 0:00 | \_ x-session-manager
joannet 15780 0.0 0.0 4252 524 ? Ss 11:49 0:00 | \_ /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session x-session-manager
joannet 15847 0.0 0.1 13080 5644 ? S 11:49 0:00 | \_ /usr/bin/metacity --sm-client-id=default0
joannet 15850 0.5 0.4 39260 14908 ? S 11:49 0:01 | \_ gnome-panel --sm-client-id default1
joannet 15851 0.5 0.5 76264 16524 ? S 11:49 0:00 | \_ nautilus --no-default-window --sm-client-id default2

This tells you that nautilus running as joannet with pid 15851 is a child of
the x-session-manager[15749], which is still also running. If the bad one you
find is not a child of a running x-session-manager, then the chances are that
person is now logged out and nautilus hasn't closed properly.

It would make things more clear to know if the process is a child or not.

This seems to be a bug in ubuntu/edubuntu 7.10. On my ubuntu 7.1 pc i
get this problem often after logging out and in again at once. I wrote a
bugreport at https://bugs.launchpad.net/ubuntu/+bug/153180 but did not
worked on the problem any longer, because i don't log out and in so
often. I also can't reproduce the problem if i want to. But it is still
there.

I think your problem is the same and is not special to edubuntu.
