This is a common message seen when a client roams from one AP to another.
Try filtering your logs for a single User MAC, and you will see these transitions to/from the APs.

Or I might say, Logs are Logs, and not to worry, but do you have Client connection problems,
is the real question?  Then, you refer to filtered logs for troubleshooting.

Hi michael, thanks for your answer, the real issue is that the clients log is shows this masaege in all the network, and some time in the final device, get discconectec.

This is log for my cell phone, when I tri to make a speed test, get disconnect and connect to the network. ap 421 get in the room -64 db by wifi analyser, and ap 321 get in the room -55 Db by wifi analiser, 

Why the roaming get disconnect the client? and if you see, there is to many leave wlans, and other log said roams out to. what can be the trouble? this issue is in all the network. Even if I am down the ap.
