USG60 High CPU

Dayna

I recently upgraded my Spectrum Internet from 100 mbps to 600.  If I set the USG60 Wan1 interface to 1G, the firewall CPU will go to 100% after a short period of time and become unresponsive.  If I set the Wan1 to 100 mbps, it runs without issue.   I'm not able to control the speed on the Spectrum device--its fixed to auto.  Any one have a resolution?

The firmware version is 4.62 .  Over the weekend, support shipped me an RMA replacement unit which I put in place and has been running for 3 days without the same issue occurring.
