Comment 2 for bug 1204456

Numerous ml2 tests are failing which seem to be related to this. Following is the list of test that are failing, along with the traceback which is for each of the failed tests:

neutron.tests.unit.ml2.test_agent_scheduler.Ml2AgentSchedulerTestCase
neutron.tests.unit.ml2.test_agent_scheduler.Ml2DhcpAgentNotifierTestCase
neutron.tests.unit.ml2.test_agent_scheduler.Ml2L3AgentNotifierTestCase
neutron.tests.unit.ml2.test_ml2_plugin.TestMl2BasicGet
neutron.tests.unit.ml2.test_ml2_plugin.TestMl2NetworksV2
neutron.tests.unit.ml2.test_ml2_plugin.TestMl2PortBindingHost
neutron.tests.unit.ml2.test_ml2_plugin.TestMl2PortsV2
neutron.tests.unit.ml2.test_ml2_plugin.TestMl2V2HTTPResponse
neutron.tests.unit.ml2.test_security_group.TestMl2SecurityGroups
neutron.tests.unit.ml2.test_security_group.TestMl2SecurityGroupsXML

All of these tests fail with the same traceback log. It seems like this is related to table "ml2_vlan_allocations"

Here is the traceback log:
