100% CPU after 2 mins

[Robert_Cerny]

Hi,

I have 5 FortiAPs of different types in our offices. The latest one FP221 goes to 100% CPU after 2 mins after boot. Did anyone experienced similar issue? I tried to upgrade firmware from 5.2 to 5.4 but it's still the same...

Thanks

Robert

Please try to disable DAARP option in the AP Profile and retry.

please post your related config here. DARRP should not make CPU 100%. Also. the calculation is done on fortigate, not FAP. 

If you happen to have spectrum analysis on, you might want to turn that off since that requires lots of CPU cycles

yes same issues for me after disable DAARP cpu back to normal

Hmm,

DAARP was off, but I had Spectrum Analysis ON for some weird reason. Thanks!
