I witnessed something very interesting yesterday.
We had a client attach a device with a static ip which happened to be the same as one of our controller service interfaces, but in a different vlan, but one that the controller has a dynamic interface in as well.
All of a sudden, all the APs on the affected controller started disassociating! It took a while to clear out the arp cache and get things settled down, but it has been stable for 16 hours since we disconnected the wired client.
As the dynamic interface is not actively in use, I have disabled it for now.
