Hi
I have some trouble with my Usermanager / PPPoE setup.
When a site goes down due to power problems or other things PPP sessions form the clients can still be seen in my RB 1100AH > PPP > Interface, even if site is down for hours!
Also if one site has flapping problems, going up/down rapidly, users cant authenticate after problem is fixed.
In log it says “PPPoE connection from was already active - closing previous one”.
An then in PPP sessions pppoe-0 appears, in stead of customer name, and it just drops.
Sometimes it helps deleting customer form UM and adding new customer with same login/password.
Does anybody else have this, or have anybody had this before and found a solution??
Help! 
I can also mention that I have had the problem for a long time, and have tried several versions, and even changed RBs.
