Hi,
I am seeing consistently across all my 3850 access switches that the io memory is very low. Is this a software bug or is it normal? Even when we upgraded to a new IOS version it did not change.

Hello,
What version of code are you running now? This is probably going to depend heavily on what features you are running. You might want to open a support ticket to have them check it out if you don't want to post your configuration here.
Hope that helps!

We are running mostly 3850 Checked a few of our switches a 24 port unit in our I.T office with a couple devices on it. And a stack of three switches handling about 100 nodes. They both showed similar specs.

I do not really know why your units would have issue no issue seen on version 03.06.05E.
If I had to guess I would be looking at spanning tree and broadcast storms or something like that that may cause massive loads and issues on your switch(es).
