2 weeks ago I started noticing that the MDS process in the Activity Monitor was using 100% CPU and wouldn't quit. Over these 2 weeks I've tried multiple things including twice getting Spotlight to re-index my volumes. I've also deleted the Spotlight prefs however none of the "fixes" have ever lasted longer than a day and now everyday at around 2pm MDS goes all crazy. Quitting the process in Activity Monitor solves the problem, but only for that day. Any way to figure out what MDS's problem is?
