vCenter High disk I/O after 7.0.2 update

After updating vCenter from 7.0.1 to 7.0.2 build 17958471,  Disk I/O on the appliance went from about 1k avg to now around 75k. The jump was so severe my Storage Team had to bring it to my attention as total I/O on our Pure SAN jumped almost 10%!

I have also noticed CPU and Memory resource utilization have drastically increased above their normal average. Look at the chart below and you can see when the update occurred. Rebooting the VCA did not help. Anybody else seeing anything like this?
