We recently ran into this. If you are using LAG on your WLC; make sure you have a port channel configured on your connecting switch. An easy way to see what is going on is to telnet into the WLC and enable debug "debug lwapp events enable" With this we saw an error message "packet 3 received, packet 4 expected"
