High CPU After 9.310-11 Update

CWanamaker
Has anyone else noticed a much high CPU usage after this update? Most of the time, our UTM's will hover around 15-20% but every once in a while, they will spike up to 85%+ and stay that way for a period of time. We also noticed that it's happening across multiple UTMs at the exact same time. Different clients, different network but a number of them spike at the same time. Anyone else had this experience as well?

    Agreed with William.  The 40+% in "wa" (wait) also indicates that the UTM is running out of resources.  I would try going to single-scan, tuning Intrusion Prevention and other ideas suggested by the link in Sascha Paris' signature block.  You might be able to take enough load off until you can get a new SG unit funded.

    Cheers - Bob

    Today I set the sophos to single-scan. First feeling is that it is now better, but I have to spectate how it performs now.

    Meanwhile I discovered that since we got the short full-loads with the UTM, mails received within a full-load ended up in quarantine with the reason unscannable - AV scanner unreachable.

    Maybe anyone else who have this problems could check if they got the same?

    Edit: after switching to single-scan, the memory usage dropped about 5% to currently 75% according to the web interface (75% of 2gb total mem).
