Sometimes this fails with lockd_down: lockd failed to exit, clearing pid nfsd: last server has exited nfsd: unexporting all filesystems lockd_up: makesock failed, error=-98 after which the server must be rebooted. I think there is something with lockd because there are no problems over the day. It is in the morning when a lot of people log into their machines and start their desktops (I think kde locks its config files when it reads them).
