WiSM - "CPU Receive Multicast Queue is full on controller"

After we upgrade to WiSM 4.1.185.0 for 5 days, we got critical

alert message about "CPU Receive Multicast Queue is full on

Controller" from one controller. We have never seen this error in previous

versions. I do not see high CPU usage on the controller now. What could be wrong?

Thanks!

If you don't have disable multicast on the controller. As a last resort consider upgrading the controller whcih fixes the bug CSCsb11342

Yes we have ethernet multicast disabled on the controller. I cannot see that bug it is saying available to employee only.

I only see this message once. I opened a TAC case and I was told it could be caused by traffic and this message should not effect anything.

Hi, can you share the outcome of this TAC case? what was the solution for solving this issue?

Please, could you share the outcome of this TAC case?

I have the same problem, it drive me crazy because I get Poor connectivity / Performance

TAC said this message should not affect any thing. We don't see any connectivity/performance issues and I am just ignoring this message now..
