UTM 120 CPU spikes

atoast217
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!

    With 9.3, I've had to make adjustments at the command line for some clients to schedule anti-virus updates around their busy times.  Reduced Intrusion Prevention rules, etc.

    Also, see Sascha Paris' suggestions: https://community.sophos.com/products/unified-threat-management/astaroorg/f/51/t/22429

    These are stop-gap measures while you and your reseller work out a deal with Sophos to get you into a new machine.  We're nearing the end of the time I disagree with William about 2GB vs. 4 for the smallest installations.

    Cheers - Bob
