EoS B2 low performance when NAC active

[Rafael_A_Souto]

We are facing really low performance on B2 with :

set eapol enable
set dot1x enable

and a RADIUS/NAC configured

The only thing we see it's that CPU usage increases a lot.

Do anyone knows if this ist's a know issue, we are running firmware 04.02.19.008 on switches.
Do anyone knows how to solve this problem?
