ISE 3.0 CPU and Authentication Latency Grows Over Time

Ciscorocks

Hello,

Has anyone seen an issue on ISE 3.0 where the PSN nodes are growing CPU and authentication latency over time? CPU has been spiking on all PSNs. These have 24 vCPUs, 96GB RAM, and 310 GB disks. I also have the CPU reservation set for 24,000 MHZ. This is 3.0 patch 5.

 

Note: If I reboot the PSN it is good for about a month before getting to the point of dropping sessions again and see the CPU and latency rise to an unhealthy level. Before upgrading to 3.0 I didn't see it get above 100ms. It has been getting up around 2,500ms and CPU is 65%.

 

Thanks.

What was the before version worked as expected, when did you upgraded to ISE 3.0 ?

 

Do you see any Logs on the switch port it connected ? (i mean any logs on in VM environment)

 

if the same VLAN other devices works as expected ?

 

There are some bug same one in the old version, they may be repeating, if this is effecting environment, worth open a TAC Case.
