I had the same problem. Hud service using GBs of RAM and CPU always at 50%+. Also the thumbnails of files in nautilus were not showing. In my effort to fix thumbnails I granted permission of ~/.cache/thumbnails for the user. then everything has solved. hud-service using only 11.5MB of RAM. CPU below 5%.
