Title:
Network: concurrent issue for create network operation
Status in neutron:
Expired
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.
Version: latest devstack
