We have a set up where there is a media server that has a webcast streaming (unicast). Any number of iPads will connect to the service and pick up the stream, but then all communication stops after approximately 5 to 10 minutes. When the iPads, as well as other platforms including Windows, intially connect they can receive the stream and ping one another. At some point, the streams stop and all the devices eventually stop responding to pings that are connected to the AP. They are able to ping upstream of the AP and thorughout the network, but they stop between hosts. If the wireless is disable and reenabled on the medai server it will again start streaming and communication resumes for 5 to 10 minutes. Below are a few log entries I've seen, but no other debug I've tried result in any messages. I've tried rebooting the controller as well as the AP.
