Navin,

   Is this happening with all subs or just certain ones?  I've seen this kind of behavior from flaky clients before.

I am having quite unusal problem. Once the user's PPPoE session is already established but still we are getting user authen request from those users. 
The log below will give you more idea of the problem. This is not just happening with one user only but with many many user. 
  
Because of this aaad process occupies high CPU load. 
  
I tried everything to resolve this but still can't resolve it. I have upgraded the SE800 version to 6.1.3.8 but no use.
