The event log for our FGT600D is full of many thousands of messages like below. All the same speeds etc but for each port over and over. I have several FGT60E's as well on the same level of OS but they do not have the same events. The 600D is in a A/P cluster. Not sure what I need to do to prevent the messages? Any suggestions?

Hardware FortiGate 600D 
Operating system Fortinet Fortigate v5.6.3 (build1547)  

OB version 17.6.8672
