Wondering if anybody else has run into this type of situation. Customer charges a large number of devices in a location at a DC and are left in the cradle, turned on since they run updates to the device during Maintenance hours of 2 - 6 am.  We seem to have found a limit to the number of devices a 1232 can support to be around 55 devices.  Once this limit has been reached the AP disconnects all devices.  At this point we have 60 devices all probe scanning to get back on the network.  The AP that just disconnected us still responds to probe scans, since it's the best AP in the area to connect to the devices attempt to re-authenticate to that AP.  The AP is so busy responding to probe requests it never has time to fully authenticate a device, device times out, probe rescans and the cycle continues.  This continues for about a minute, then all devices go into hibernation to conserve battery, hibernate for the same amount of time then all 60 wake up and begin probe scanning for another 10 seconds, timeout and go back into hibernation for 5. This is clearly an AP load issue, customer is planning on swapping 1232's for 1242's in that area which should support more devices but there is the potential for this to happen at other locations of the DC of 1232's.
