5.0.2.0 Sup-1 100%cpu

Hello there,
Is there anyone getting a high CPU utilization on their controller with 5.0.2.0?
We have 3 local Sup-1, 88-110 APs each, all running +90% after we get more then 300 users on a controller. We are also seeing SNMP timeout when our Airwave tries to poll the controllers, causing huge amounts of false downs.
I do have a ticket open with support and the stop gap is to restart the snmpd module on the controller (helps sometimes, doesn't fix the issue completely). Just trying to get a feel if I am over loading the controller.
thx

Polling Time

What is your polling interval on Airwave?

Standard

Your polling and that amount of clients and APs is a fairly standard deployment and we have seen a number of customers upgrade to 5.0.2.0 with that platform without the high CPU that you are seeing. Support would best be able to advise if we have seen anything lately with that version and that platform.

Us too

We are seeing a similar issue. Datapath utilization and/or CPU utilization spiking towards/at 100%. These are SUP2s with nearly 256 APs on them and about 800 (+/-200) users.


Did you hear anything new from engineering/support?
