Symptom
Cat9K stack - We may see standby reloads due to config-sync failure while adding/removing ingress QOS service-policy at certain conditions. The issue is seen on 16.11.1C but it might be seen on other main releases as well.
As long as manual configuration of service-policy is done on a port where same policy was once pushed by a dynamic template/ISE, the config-sync failure is seen consistently and the reload triggers while removing that ingress QOS policy from the port.

Conditions
As long as manual configuration of service-policy is done on a port where same policy was once pushed by a dynamic template/ISE, I see the config-sync issue consistently while removing that ingress QOS policy.
