Just noticed that on the Dashboard one cpu at a time goes to 100%.  Running top shows wsdd taking 100% (I am assuming that means 100% on one processor).  It jumps around to both regular and HT processors, all of which are not pinned to a VM.  It does not seem to be impacting any function or performance; I have not seen this before upgrading to 6.8.0.  I do not see any issues in the system log.
