6.4(1a)

Description (partial)

Symptom:
Traffic is dropped and users cant connect to the server on DC side. eventually when the cma process is restarted it should optimize the traffic but here traffic is dropped.

Conditions:
topology:

customer is having iWAN setup service-insertion is enabled on the tunnel interface. loopback interfaces should be used as appnav-cluster interafce and router to CM communication.

steps tp repro:

we could recreate the scenario by manually restarting the cma process, but for customer it has restarted due to some AO TIMEOUT issues.
