First off: Symbol and Cisco don't play well together (at least in some configurations).
There are also issues in some cases where the Symbol APs, plugged into Cisco switches (or probably anyone else's) don't "hand off" on a roam cleanly - the switch sees the same MAC on two ports and declares that the interfaces/switch/blade is "flapping."
Also, remember to read your log from the bottom up: the most recent event is at the top.
What appears to have happened, with the information that you've posted, is that the client got to far away from the AP (or something got in the way), the AP dropped it when it failed to respond (with an "ACK" to the info previously sent).
Once the client came back into range (or the interfering element moved out of the way), the AP was able to reassociate the client.
I was not very clear in my original post. The access point is a Cisco 1200 and the devices are in a small room with the Access Point. I am wondering if the device is not used for some period a time if the message could also be received? If yes what is the length of time.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

The script should be completely self explanatory.
