Description (partial)

Symptom: A Cisco ASR1002X production router acting as a WAN-Aggregator reloads unexpectedly after pushing the AVC configuration from Cisco Prime infrastructure through an SSH session.

The configuration push was successful onto the box, and the flow statistics were exported to the PI. 

However, after 30 minutes, the router reloaded with a "CPP mcplo_ucode" crash and a "fman_fp" crash. The box is configured with IKEv2 DMVPN and basic NAT, along with BGP and EIGRP. Four static NHRP tunnels from different branch locations terminated onto this box. All traffic from the branches were encrypted, decrypted on this router and NAT was applied to the decrypted traffic before sending it out of the port-channel interface towards the production network.
Conditions: This symptom is observed on a Cisco ASR1002X router running CCO IOS-XE version 3.10.1 The crash has occurred only once. Currently AVC configurations have been backed out and the router is stable. This affects the AVC deployment on the network seriously.
