I have WLC 2500 with 6 AP updated LWAPP
since Jan, 2014, there were 2 APs frequency made following message in log of WLC:
May 5 00:24:46 x.x.x.x kernel: wlc-2504: *spamApTask5: May 05 00:24:46.647: #LWAPP-4-DATA_PLANE_ECHO: spam_lrad.c:31095 AP APName reported timeout communicating to controller on data plane.
There are more than 900 that message per day on message log.
Please help to know how to fix it.
Thank you very much!
