High kernel CPU and memory utilization on ACI leaf switches

[sina.naser]

Hi everyone,

In Our ACI fabric We have 6 leaves and 2 spines. 

the user cpu and memory are normal.

But the kernel CPU and memory are always between 80% and 100%.

our APIC and switches version are 5.2(3e) and 15.2(3e) in order

Any ideas might help

Tnx in advane.

Hello Sinaa

did you check your current ACI Leaves and Spines Capacity?

[sina.naser]

Yes, all parameters are less than 10 percent

[jairhern]

are you experimented some connectivity issues?

Hello Sinaa

Sounds like a bug

I think you need upgrade your ACI devices ,the fixed version is 15.2(6e), I think this issue (kernel CPU is a cosmetic bug)
