 I would say that this logs you are showing is consequence, not cause. If you explore the Assurance, you may get some information on why clients are disconnecting. 

Take a look on the feature " Intelligent Capture". This might give you the answer.

Please provide a little bit more detail, like if this was a new deployment, any recent upgrades or changes? Also you need to at least be onsite to do some testing to help gather additional information. Does mobile devices also experience that issue or maybe a Mac? You need to look more on the controller logs and debugs while you are testing. This can just be maybe how you have the wlan configured which is causing this issue. Make sure these are valid clients also because users might be trying to connect their mobile devices or users outside of your organization is also trying to connect.  That is why you need to isolate the devices and go onsite to really test. See what is really happening and get feedback from the users you see valid devices stuck on the onboarding state.
