The most likely cause of this problem is communication errors between
the frontends and the backend.  When you had 100% CPU, there was a
reasonable likelihood that the backend was not responding in time and
the frontends were detecting that.  Since the 100% CPU problem seems
to be fixed now, I would suggest that you start checking out your
ethernet (or is it WiFi) traffic levels.  It is possible for something
else other than MythTV to be using too much of the bandwidth and
preventing timely access from the frontends to the backend.
