Public bug reported:

We are continually creating new networks, subnets, routers and ports.
Afterward created port is attached to one of two existing VMs. When this
run come to around 30-35 networks an MessagingTimeout error starts to
appear in log.

Example of creating one network:

neutron net-create vxlannet3 --shared --provider:network_type vxlan
neutron subnet-create vxlannet3 1.1.3.0/24 --name vxlansubnet3
neutron router-create r3
neutron router-interface-add r3 subnet=vxlansubnet3
neutron port-create vxlannet3 --name vm-3-port

nova interface-attach --port-id=`neutron port-list | grep vm-3-port |
cut -f 2 -d " "` $vm1

Log attached.
