$ neutron-server --version
neutron-server 2015.1.0
Reproduce the bug:
1. Two network node running l3, dhcp, metadata
2. ml2 ovs + gre
3. enable neutron l3 ha
4. create ha router
5. set router gateway
6. add router interface to a subnet
7. create an instance
8. set a floating IP to the instance
9. unset and release the floating IP
10. unset the router gateway and the interface to a subnet
11. delete the router
And then error comes:

This message:
"Error during notification for
neutron.agent.metadata.driver.before_router_removed router, before_delete"
came from the code:
class MetadataDriver(object):
def __init__(self, l3_agent):
self.metadata_port = l3_agent.conf.metadata_port
self.metadata_access_mark = l3_agent.conf.metadata_access_mark
registry.subscribe(
after_router_added, resources.ROUTER, events.AFTER_CREATE)
registry.subscribe(
before_router_removed, resources.ROUTER, events.BEFORE_DELETE)
The router resources was deleted, but it seems that the Metadata was
not notified.
