CSCuz11169 - High memory utilization observed on catalyst 3650%2F3850

Can anyone confirm the fixed release in 16.3.x?

The DDTS Bug notes state 16.3.1, but also say 16.3.1 is affected.

The release notes state 16.3.1 and 16.3.2 resolve this caveat.  However, I think I'm seeing this caveat in 16.3.3.

 

Thanks in advance.

Unless there is an urgent need to, I'd avoid 16.X.

Agreed. However, I need to run 16.x to meet design requirements.

Ok, then look for an IOS-XE version that doesn't end with .0, .1, or .2.  Look for something with a higher "suffix" number.  This means that the train is being "fixed" or updated.

Geez. That's still high.
However, give it a few days for the stack to "calm down".

Looks like something triggers this,  I have 5 additional stacks running on this same version and memory looks a little bit high but reports as healthy.

We experienced this issue as well while running 16.3.5b code, we upgraded to 16.3.6 which is the current starred release code and so far the memory looks good. We are running stacks of 7-8 switches per stack.

We're having the same High Memory on Control Processor issue with 16.5.3b. Have you experienced the problem on 16.3.6?
