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

I haven't looked at the command line of a CAS in a year or so, but if I
remember correctly, on the CAS it was always normal for the kclick to replace
the CPU idler.

We are exact same as you...Virtual Gateway In Band on two 3140's.
Whether I have 0, 50 or 200 users online, kclick is always using 95-99%. TAC
told me it
was nothing out of the ordinary...
I'm still skeptical though...

Subject: NAC 4.7.1 Upgrade - High CPU on CAS
Just upgraded my test NAC system (1x3140 CAM, 1x3140 CAS) from 4.6.1 to
4.7.1. The "kclick" process on the CAS is taking 99% of my CPU, and there
is nobody on the system! I recall someone else posting with this same
issue. I'm in Virtual Gateway Inband mode. Did anyone find a cause?
