Just did the upgrade to 4.7.1 and my CPU is being pegged by kclick now:

Not too sure what this means .....

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:

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