[mythtv-users] High CPU usage after latest update 25.fixes

I am running 25.fixes and have not updated in a while. I updated my two
front ends and the back end yesterday. Myth-backend is showing real high
CPU usage. Top shows 252% for myth-backend, and 118% for mysql. Mysql dies
down when I shut the backend down. Memory footprint looks about normal on
myth-backend and mysql. All six of my cores are running about 90%. Nothing
is going on, no recording, no live TV, no transcoding etc. OS is latest
ubuntu LTS fully patched, except for the latest kernel. I can watch videos,
and recorded programs just fine. Have not tried live TV, but my wife told
me that it was not working before I put in all the upgrades. Mythweb
reports nothing going on.

Backend log shows nothing but the housekeeping thread and auto expire.
which is normal.

I have restarted the backend and it goes right back to high CPU usage on
start up, which is sustained for the last 6 hours.

Is anyone else having this problem?
