HTTPProx using up CPU

njorge
We're having an issue with our UTM 425 where the httpprox process will start to gobble-up CPU. Normal CPU usage here is about 10-20% during peak hours. But occasionally I'll see it spike up to 40% and stay there indefinitely. When I SSH in and run top, it looks like httpprox is pegging a CPU.

I can then toggle web filtering off/back on via the web gui, or reboot, and the problem goes away until the next day.

Our re-seller doesn't see anything obvious. Where should I begin troubleshooting?

    oh there was some kind of bug involving a/v and single scanning.  Frankly i would try dual-scanning and leave it on..greater security.  it will increase cpu but unless it starts affecting performance the extra security is worth it.  I always run dual-scan a/v.


    The issue returned. Attached is a CPU usage graph. Around 11:00 AM, you can see CPU usage spike and stay there. SSH'ing and logging in, httpprox is using up a full core of CPU.

    i am really surprised you don't' have a larger load than that with 700 users.  If you'd like i can take a quick gander.  I would also get support involved.  The web protection logs should give us a clue.
