Race condition: returns 404 when listing ports

[Thomas Herve]

I've observed this behavior in heat integration tests: http://logs.openstack.org/51/271451/1/gate/gate-heat-dsvm-functional-orig-mysql/9f09db7/logs/

When creating a server, nova calls list_ports and it fails because a network can't be found: http://logs.openstack.org/51/271451/1/gate/gate-heat-dsvm-functional-orig-mysql/9f09db7/logs/screen-n-api.txt.gz?level=ERROR

As it turns out, the network has been removed after the list ports has started, thus making it failing.

It should handle that NotFound and ignore the error, as there is a transaction issue somewhere.

http://logs.openstack.org/51/271451/1/gate/gate-heat-dsvm-functional-orig-mysql/9f09db7/logs/screen-q-svc.txt.gz?level=ERROR is the neutron side failure.
