We have installed 20 mesh access points (x16=1522AG, 1131AG) controlled by 4402 Wireless LAN Controller (WLC) version 5.2. The network is currently up and running. The problem is that some access points disappear from the controller and then reappear. I captured some message logs in the WLC shown below:
5 Fri Feb 19 11:55:53 2010 Mesh child node '00:26:0a:39:65:0f' is no longer associated with mesh node '00:26:0a:38:6e:00'.

The Mesh access point above is a Mesh Access Point (MAP).
Someone pliz explain the logs or the intermittent disappearance of the Access Points.
