Message #51892
[Bug 1588593] [NEW] If Neutron IPAM driver is setted，using 'net-delete' command to delete the network created when ipam_driver is not set，the command seems to cause dead loop.
Public bug reported:
In Mitaka,
When ipam_driver is not setted,created a network with a subnet,then using the reference implementation of
Neutron IPAM driver by setting 'ipam_driver='internal'',and using 'net-delete' command to delete the
network created when ipam_driver is not set，the command seems to cause dead loop.
1)Specifying ‘ipam_driver = <None>’ in the neutron.conf file，created a network with a subnet

3)Deleting the network returns none,and dead.,
the usage of neutron-server is above 80%，and neutron-server's log is repeating “ERROR neutron.ipam.drivers.neutrondb_ipam.driver [req-fd43f9e3-9423-41bc-8434-7787bab0f263 admin 69fa49e368d340679ab3

Title:
If Neutron IPAM driver is setted，using 'net-delete' command to delete
the network created when ipam_driver is not set，the command seems to
cause dead loop.
Status in neutron:
New
Bug description:
In Mitaka,
When ipam_driver is not setted,created a network with a subnet,then using the reference implementation of
Neutron IPAM driver by setting 'ipam_driver='internal'',and using 'net-delete' command to delete the
network created when ipam_driver is not set，the command seems to cause dead loop.
1)Specifying ‘ipam_driver = <None>’ in the neutron.conf file，created a network with a subnet

the usage of neutron-server is above 80%，and neutron-server's log is repeating “ERROR neutron.ipam.drivers.neutrondb_ipam.driver [req-fd43f9e3-9423-41bc-8434-7787bab0f263 admin 69fa49e368d340679ab3
