Cisco ISE high memory on all nodes
« on: April 23, 2016, 11:26:26 AM »
Hi everyone,

another issue I have noticed with my ISE deployment is that almost all nodes are constantly running at 80-85% memory utilization ( I have 32GB per node, 3495's).
This makes no sense as some of my PSN are not authenticating any users yet.
psn3/admin# sh memory
total memory:   32880364 kB
free memory:      689036 kB
cached:          4661596 kB
swap-cached:           0 kB

output of free command:
             total       used       free     shared    buffers     cached
Mem:      32880364   32191328     689036          0     197960    4661596
-/+ buffers/cache:   27331772    5548592
Swap:      8185112          0    8185112

psn3/admin# sh ver

If there is absolutely no traffic hitting your standby PSN then this is obviously not normal. There has been history of high memory utilization in 1.3 with certain patches so it wouldn't surprise me if it returns in 1.4. The best way is to probably check with TAC and have them search for bugs.
