[octavia] Management Network Issue

Hi, I am using octavia 9.0. I have created a neutron vlan based management network of octavia. I am creating a loadbalancer with a subnet in the tenant network, its getting created successfully. Then added a listener and created a pool, both created successfully. Now a weird situation is happening. Now when I add a member in the pool, the management network interface get detached automatically from the AMPHORA instance and amphora keeps in PENDING_UPDATE state. I have created a dedicated service-project for octavia and management network and subnet resides there. Any advise how to fix it ? Ammad
