After Upgrading our PA-820 to 11.0.2, we're seeing lots of data on dns-base application.

After Upgrading our PA-820 to 11.0.2, we're seeing lots of data on "dns-base" application.  In a 24-hour period, I'm seeing 5PBs+ of data coming through, which is way over our limits for our internal network (two DNS servers at 1GB NIC each) and external network.  Our ISP bandwidth is 500/500 Mbps.  So it's going way over our MAX capacity.  However, if you look at the Management Plane and the Data Plane, they are both under 25%.  I'm thinking it's just not showing the numbers properly.  The DNS Servers that supposedly are communicating with external DNS Servers (8.8.8.8, 1.1.1.1, OpenDNS, etc.) are not showing tons of traffic.
