Public bug reported:

If server with neutron-server service have not enough resources for fast
processing of requests then there is a high risk of multiple port
created for VM during scheduling/networking process.

How to reproduce:

Just get some environment with not so fast neutron-server service node and/or mysql server. Try to spawn bunch of VMs.
Some of them will got two ports created (in neutron DB they will have same device_id). If the system is very slow they could get three of them. If VMs would be spawned it will have only last one which nova got from neutron and this port will be the only active one.
