This is from a 3310 that only has the 4.7.1 OS installed. Nothing else has been done to it yet. It's a new CAS right out of the box. Tomorrow I will be doing the upgrade on the production CAM and CAS and then adding this box:
[root@cas3-2fl-3310 ~]# top
top - 07:48:14 up 20:30, 1 user, load average: 0.02, 0.01, 0.00

Hope this helps

This is my production CAS (3140) running 4.1.6 lightly loaded:

This is my test CAS (3140) running 4.7.1 with NO load:
[root@test-cas ~]# top

Is anyone running 4.7.1 on one of the newer appliances like the 3310 or
3350? If so, is the same thing happening?
