Comment 53 for bug 1249065

While testing our current Kilo cloud, we're seeing a lot of occasions of this in the following tempest tests:

tempest.api.compute.floating_ips.test_floating_ips_actions_negative.FloatingIPsNegativeTestJSON.test_associate_nonexistent_floating_ip[id-595fa616-1a71-4670-9614-46564ac49a4c,negative,network]

The error messages are always very similar:
