3850 Stack slow console, high cpu 1.

[jasonmeyer]

Have a stack of 3 3850's and its behaving really slowly. I think there was a reboot about 3 hours ago. When I do a sh ver, the mode of all 3 switches is Install and model for one switch is MODEL UNSET. There are a few ports on that switch that are amber but if I move them to another port they stay amber.

A little more info. 

Switch 2 and 3 in the stack have high CPU with stack-mgr process the highest. Switch 1 seems to be ok.

And these two are all i see in the logs.

%PLATFORM_PM-2-ASYNC_WAIT_TOUT: PM wait for ack timed out: req_id 988, dest slots:0x8, ack pending from slots 0x8

%EM-4-AGED: The specified EM client (EM_TYPE_PM_PORT_ENABLED type=21, id=33137)
did not close the EM event within the permitted amount of time (300000 msec).

Hi,

What is the model of 3850 and what software is running on them. Have you checked the stack cable connections and reboot the stack?

Thanks

John

I did end up rebooting the entire stack, after I tried to reload the problem switch.
