Configuration of PPPoE Profile for PPPoE Service Selection causes 100% CPU utilization on ASR 1000

Hello,

the following configuration steps lead to 100% CPU utilization on ASR1001-X. 

1. enable
2. configure terminal
3. bba-group pppoe {group-name}
4. virtual-template template-number
5. service profile subscriber-profile-name

High CPU utilization is caused by SSS Manager process. Utilization remains 100% until either the router reload, or un-configuration of bba-group (which sometimes lead to crash).

ASR1K#sh proc cpu sorted 
CPU utilization for five seconds: 99%/0%; one minute: 48%; five minutes: 13%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
215 32731 68087 480 76.87% 36.76% 9.42% 0 SSS Manager
677 4198 70747 59 9.67% 4.62% 1.18% 0 PPPoE Background
471 2956 34043 86 7.03% 3.29% 0.84% 0 LOCAL AAA

This behavior has been observed on IOS XE version 16.9.6 or 16.9.7.

Does someone has the same experience?

Best Regards,

Peter
