RFS6000 ---- CPU load averages : 1 min: 99.9% 5 min: 99.9% 15 min: 99.9%

Hello,
We have a RFS6000 WIFI controller and currently I have 100% processor load.
- service show diag stats :
CPU load averages : 1 min: 99.9% 5 min: 99.9% 15 min: 99.9%
Processor use by processes seems correct.
- service show diag top

I do not understand the cause of this processor overhead !!!
Someone can help me
Thank you

We had the same thing happen to us about a week ago. Still waiting on the Root Cause. We ran the "service show process" command and saw the CFGD process taking 99% for more than 24 hours. So far Support is saying a script was running and got hung up. Like I said though, we are still waiting on the root cause after we uploaded all tech-support files before reloading the controller. Since the reload, all has been good.

Suggest you get a case open before you reload and do a "service copy tech-support ftp://xxx.xxx.xxx/file-name to a local drive. When you open the case you can upload the tech-support file for them to analyze.

Hello Shay Weir;
Thank you for your prompt response. Indeed, for my case, all the processes work correctly and I do not see a process that uses much processor !!!!

Is there any scraping that goes on in the background for information on devices the RFS is controlling? We had an issue where all 150 of our devices were being scraped by an external process which would login and run a script every X amount of seconds. I would also have a look through the best practices which goes into some causes of high CPU load: http://documentation.extremenetworks.com/WiNG/Implementation_Guides/WING5X_Reference_Best_Practices_...

What version of firmware is the controller on?

Here's a link that might help: High CPU Utilization of process cfgd on WM3000 controller

You are running firmware WiNG 4.x the above kb article does not apply. KB states that in firmware WiNG 5.5 CDP is enabled by default, while in earlier versions CDP was disabled by default.
