Can you please provide the details of
1. Contrail version info
2. Setup information (single config node[all in one] or with multiple config nodes)
3. also attach the tar of log file from /var/log/contrail.

Do you see issue after issuing port-list or infinite loop is seen after the port-create itself?

1. contrail master branch
2. Single node (Ubntu 14.04 + devstack + contrail)
3. tar file attached

Reproducing steps:
neutron net-list will show private network, if not create network private
if no subnet, create subnet for private network
create port
Restart api-server
After api-server restart, private network will not be listed under neutron net-list
create network private
create subnet
create port
Check api-server logs, this will be in infinite loop
