Hey

theres a few open bugs for this FED process on 3850s , if your not on this image i would go to it.

Its stable and should fix majority of open bugs 3.6.3

This is how to troubleshoot FED but it shouldnt be spiking cpu like that its the engine driver for the switch

I have 03.07.00E version installed in all my switches

Hey the reason i suggested 3.6.3 you will see on Cisco website it has been marked as safe harbour , it also runs clean on McAfee MVM vulnerability scanner too, im running 3.6.3 on our switches and do not have this fed issue, just becasue its a later version does not suggest it may be more less susceptible to issues. If you dont believe its the image the troubleshooting doc should be able to provide some tips to narrow down what it may be

Safe Harbor certification marks the successful completion of extensive integrity testing that validates each release
