Hello.
I am getting a Critical controller error on my WCS panel that says "CPU Receive Multicast Queue is full on Controller 'xxx.xxx.xxx.xxx'. "
I have blanked out the IP above- it's the controller's IP address.
What exactly does this error mean, and what can I do to fix this? I haven't had much luck in finding information on this particular error and it's starting to bother me.
It triggers a couple times a day, or sometimes several days apart.
My controller is running version 4.1.171.0 and my WCS is 4.1.83.0.
Thanks!

Hi Peter,
There is a bug filed for the same CSCsf27201. Sometimes even when you are not using multicast traffic ,ARP and CDP packet keep hitting controller CPU and reports this message. Although these packets are dropped when que gets filled but WLC reports this message which will is already resolved in upcoming release.
This message will not affect your network in anyway.

I had the same issue. I'm running the same code on my WLC's. I called TAC and its a bug CSCsj72274. To fix the issue I had to enable CDP on the controllers. Type in these commmands for the controllers CLI:
To see if CDP is enabled: show cdp
To enable cdp: config cdp enable
Once I enabled cdp my controllers acted normal, and I stopped receiving the Multicast error.
