How to Troubleshoot High CPU utliization on the Ruckus vSZ-D virtual machine

[scott_crace]

We are currently running our environment in two virtual machines: Ruckus vSZ-E and vSZ-D
According to the webUI we're running the following:
Controller Version 3.5.1.0.296
Control Plane Software Version 3.5.1.0.205
AP Firmware Version 3.5.1.0.419

We have a total of 10 x R720 and R610 APs in 1 zone with 3 AP Groups. Not a large deployment. Our subject matter expert left the company recently and I'm trying to walk through the training/documentation to become familiar with Ruckus.

Recently we've started experiencing our vSZ-D instance running at 98% CPU for long periods of time. I'm at a loss on where to begin troubleshooting this. I am able to SSH to the device and login/enable.

I've tried a few things on various posts and the tried and true graceful shutdown/restart. Could someone point me to a KB article or troubleshooting steps to start digging deeper?

Any news on this topic? We have a client with the same problem, but with Nutanix

Hello @Evandro,

As discussed in this thread, it is not an issue on vSZ-Dataplane, but the behavior of Intel DPDK poll mode driver. For more information please refer the below KBA.
