AIR-CAP1552C-A-K9 CPU 100% Utilization

[daniel.diaz.g]

Hi, community,

I'm presenting an issue in my AP AIR-CAP1552C-A-K9 is raising the CPU utilization to 100%, I would like to know if this problem is coming from a known Bug. 

In the Show Process CPU I saw this info too:

Device#show proc cpu
CPU utilization for five seconds: 100%/0%; one minute: 100%; five minutes: 100%

PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

....

59 949346508 112540706 8435 99.44% 99.36% 99.32% 0 NCI Rx

Always state what version of code you're running - especially relevant for identifying whether a bug is relevant!

CSCvk59498 actually says to track CSCvu02448 for the full fix.

CSCvu02448 unhelpfully only shows AP code versions not WLC versions so you need to map those back to the relevant controller release using https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html#ctr-ap_support
