I hit it again here today

http://logs.openstack.org/60/111660/13/check/check-tempest-dsvm-full/d0f4d9b/logs/screen-n-net.txt.gz

really confusing me is following log

WARNING nova.network.manager [req-49960ae4-3327-4770-8ff1-e1002786ee79 ServersAdminNegativeTestXML-863236903 ServersAdminNegativeTestXML-1636622346] [instance: 7f330ee3-90fb-463f-a325-f4a8bd7c3a02] Quota exceeded for project 5e8c727ff61142d9a7ad424cdb8ca8b5, tried to allocate fixed IP. 0 of 99 are in use or are already reserved.

from code analysis, it should not report an exception because the used count is 0
I checked quota related code but I can't see any useful log to indicate why quota failed to allocate

so ,I will ad more logs to _raise_overquota_exception and see whether we can know what happened
