Comment 7 for bug 1110807

I cannot repro this with mysql using master. Perhaps its specific to postgresql ?

Here is my test, it would be good if you could try it on your setup:

set port_quota in quantum.conf to -1 (unlimited) and restart quantum-server

In one window, i run:

quantum net-create test1
quantum subnet-create test1 10.0.0.0/24

Then I start two windows in parallel with the same command:

for i in `seq 1 50`; do quantum port-create test1 | grep fixed_ips; done

I don't see any instances of the same IP being allocated, even though there does seem to be interweaving based on the fact that the same window sometimes gets two IPs in a row.
