Description (partial)

When ISE is configured with large Internal User store, ISE is showing 2-5 seconds delay in sending the Radius Access-Challenges to the WLC. This delay creates AAA Error 'Out of Memory' errors on WLC.

Increasing the Radius Server timeout on the WLC does not help much since the WLC is waiting for the Radius response from ISE and with multiple EAP requests coming on WLC, the Radius queue gets filled up causing AAA Error 'Out of Memory' errors on WLC. The client gets deauthenticated and the EAP transaction starts again.
