Bug Description
High level description:
When running rally test-cases in parallel against the network creation API it is possible to encounter errors while attempting to update a segmentation allocation record in the DB. This results from querying the database to find a free entry and then updating the tuple in independent operations without any sort of mutual exclusion over multiple users. Since the neutron API is implemented with multiple child processes it is possible that a collision will occur when two processes attempt to access the same DB tuple.

So, you still want to raise https:/ /bugs.launchpad .net/neutron/ +bug/1800599 ? Just read your analysis, seems this is the same with the https:/ /bugs.launchpad .net/neutron/ +bug/1800599 . So maybe this is a common/know issue.Right? Could you please test more cases about other resources and other operations? Or this issue just be hit during network creation in parallel test?
