>
> When provisioning a cluster via the blueprint api, occasionally a database
> deadlock is detected. There is retry logic around this code so it doesn't
> affect the creation of the cluster and a user wouldn't notice this unless
> they looked at the logs. That being said, this issue involves incorrect
> transaction demarcation and synchronization and is potentially serious
> depending on how it is manifested.
