Symptom
A router crashes while making changes to an AppNav policy map or a class map.
Conditions
This symptom occurs under the following conditions:
- Multiple AppNav controllers are used.
- Sessions are created and can be seen using show service-insertion statistics sessions.
- AppNav policy map and class map is modified when live traffic is redirected by AppNav.
- Policy map or class map change results in a mismatch between AppNav controllers.
Workaround
When using AppNav Controller Group with multiple ACs, avoid changing the policy map or class map when there are active sessions present (use show service-insertion statistics sessions).
Further Problem Description
A crash occurs after a policy map or class map change results in changes to the existing session and subsequently a new connection matching this session is synced to the other ACs which are not aware of the new policy map or class map.
