High CPU Usage on PPPoE user Terminination...

Team,

We have CCR1036 with PPPoE, NAT, Firewall Filters enabled, HOTSPOT in the same device with 700 customers.

We are facing a strange issue of High CPU Utilization on all cores while PPPoE users getting teriminated because of link inactive or peer not responding.

CPU Usage SPIKEs while user disconnected.
