    Default Post-upgrade issues w/ excessive DNS requests coming from internal interface?

    After upgrading the other day to the latest codebase, I noticed that my bandwidth report was through the roof. After doing some investigating, I saw that the internal interface was showing abnormally high DNS traffic. After I couldn't figure out how to resolve, I decided to reboot. Once I rebooted, this "mystery traffic" disappeared. Here's a screenshot:DNS_Firewall.png

    I opened a ticket w/ support but have not heard anything back from them. Any thoughts out there?

    Support has been no help in discovering what is causing this. I am seeing the issue again. I'd like to have support look at it before I reboot to resolve again. This is insane. I'm seeing 100MB of DNS traffic passing from the internal interface with a destination of the internal interface on a regular basis when this occurs. Is nobody else seeing this on their updated firewalls?
