Ok. The current set up does not call for a voice network yet. So it was not added. Because I knew voice was going to be installed at a later date I went ahead and added it to the switch. CPU instantly dropped down to 25% and continuing to hold. Again I am on 16.3.6 with a stack of 4 3850's being used as a layer 3 device.
Thank you for the help.

Unfortunately I am not able to upgrade to 16.6.X. We are limited to 16.3.X and the latest 16.3.6 is what we are using. This is only happening on this one device, however this is the only device that is running layer 3.
Thoughts?

I have a stack of 5 WS-C3850-48P running IOS 16.3.6.
A newer IOS has not been authorized yet for my company so upgrading IOS is not an option.
I saw a bug in the older IOS 16.3.3 that the IOSD ipc task would max out the CPU. I have multiple 3850's running 16.3.6 with no issue but in one case the IOSD ipc task is causing the CPU to run at a constant 70 to 90 percent.
I am monitoring this device's CPU with Prime Infrastructure 3.4 and below is a copy of the command "show process cpu | ex 0.0"
Any help would be much appreciated.
