Hi all,

I'm having issues with Neutron on Kilo 2015.1.0. Quite often (but not
all the times) when I create a tenant network, attach it to a router
which is attached to an external network I get "Deadlock found" and
"DuplicateEntry" error on neutron servers, and the dhcp and router
ports of both networks goes in BUILD state. As a consequence, the VM
interface is not working.

I have described in more details the issue on this bug report:
https://bugs.launchpad.net/neutron/+bug/1479818 but since it's a
blocking issue for us I'm asking the list if someone else had similar
issues and has at least a workaround.

thank you
Antonio
