UTM 120 CPU spikes

Hi,

I have a number of UTM 120s deployed for different clients. Several of these clients are now complaining that they occasionally lose Internet connectivity for periods of 30 seconds to a minute. VoIP call quality also decreases during this time.

I've verified that every time, I'm seeing CPU spikes to 80-100% on the UTMs.
If I turn off Web Filtering, the problem goes away, but I don't like leaving that off.

I've rebooted the UTMs, updated them, checked settings for anything I can limit, and nothing seems to be working.

Do I have bad UTMs? Is there a recent firmware update that increased resource usage? Are they just overloaded?

I'd appreciate any help. I'm stuck.
Thanks!

I have a 120(hardware) with basicguard which disables ATP and that mitigates the issue..interesting...[:)]

CPU spikes are definitely related with savi up2date procedures. During that time webadmin is not available and CPU is at 100% constantly.
Here is my observation on a client's UTM120:
