Indexing - Connected? - CPU Use?

Hey all,

ok, so we all know that WD Crapped the bed when it comes to the OS 5 and how it indexes.
My indexing seems to be finally completed (after a 2 month long process!), now in the Cloud Access information it says “Connected (Generating Previews)” so am I to assume that this is now completed?

What’s odd is my CPU is still going snake crazy! Anyone know why the CPU would still be pushing 90% use?
