A NIS (2013) upgrade persists in running resource-heavy file system scans while my 32-bit XP Pro (SP3) desk machine is under use. As a result applications hang, videos stutter/stall and the GUI freezes and at times becomes non responsive. My dual RAID drive configuration roars away like a pnueumatic jackhammer. The pervious 2012 install always stopped scanning when expected - even with as little "activity" as slightly moving the mouse pointer. I've checked all the NIS user settings and they seem normal. Any ideas?
