Hello Team,

we have Cisco ISE PAN, SAN and 6 PSN..

PAN , SAN and few PSN are showing around 100% memory utilization.. but not giving any error.

Recently we have installed certificate on PSN and due to that they have rebooted as well but still memory utilization is high..

Version : 2.7.0.356
Build Date : Thu Nov x 02:21:59 2019

- Allocate some more vram to a (test) node , check if that can help , then evaluate increasing vram for other nodes too.

Please clarify how you measuring the memory utilization. Depending on the means, it might be normal. Good to check tech-support as Marcelo Morais suggested.
