and

  • Single or multiple device packet flood - Denotes that an AP has detected that single or multiple client(s) have attempted to flood the wireless environment with a type of packet. These message can indicate a malicious attack or temporary, client-based misbehavior. 

 

If its one of your clients maybe the client is somewhere stuck on the authentication proces and keeps trying?  If its a unknown  client it could be some kind of attack.

But im just guessing here..
