Ran into this problem with a stack of 2 3850 switches.
*%OSAPI-4-CPU_OVERLOAD:Switch 2 R0/0: wcm: Warning! Task 6585 (wcm) is taking 143% (0% user 143%system)of the cpu!.

It caused switch 1 to drop from the stack and anything connected to it lost network communication. Switch 1 came back but I dont have any scheduled tasks running on the switch, so I'm not sure what's cuasing this. Any help is appreciated.

Most likely an IOS bug. You should open a ticket with TAC and send them the info. Most of the time they will recommend an upgrade.

It's version 16.3.1. We opened a ticket with our MSP on it and sent them a 'show tech' output.

I can't speak for the 3.6.x train, but from my experience, the 3.7.x train is garbage. We had constant bugs with 3.7.1 and 3.7.3, until we moved to Denali 16.3.5b.
