Message #36282
[Bug 1479818] [NEW] "Deadlock found" and "DuplicateEntry" errors when trying to attach a neutron L3 HA router to an internal network
Public bug reported:
On a setup with 2 neutron nodes, L3 agent in HA (VRRP), we get errors
while attaching a router to an internal network. How to replicate:
* create the external network (vlan)
* create an internal network (vxlan)
* create a router
* attach the router to the external network
* attach the router to the internal network
After attaching the router to the internal network, the following
happens:
a) some router _and_ dhcp ports of the external networks go from ACTIVE to BUILD status
b) dhcp ports of the internal networks go from ACTIVE to BUILD
c) two type of errors are found on the neutron log file:
- a **Deadlock found when trying to get a lock** error, on one of the network nodes
- multiple **Duplicate entry ... for key PRIMARY** on both network nodes
How we replicated the issue

* 3 RabbitMQ cluster
* All nodes running Ubuntu Trusty and Kilo 2015.1.0 from `ubuntu-cloud.archive.canonical.com`

Title:
"Deadlock found" and "DuplicateEntry" errors when trying to attach a
neutron L3 HA router to an internal network
Status in neutron:
New
Bug description:
On a setup with 2 neutron nodes, L3 agent in HA (VRRP), we get errors
while attaching a router to an internal network. How to replicate:
* create the external network (vlan)
* create an internal network (vxlan)
* create a router
* attach the router to the external network
* attach the router to the internal network
After attaching the router to the internal network, the following
happens:
a) some router _and_ dhcp ports of the external networks go from ACTIVE to BUILD status
b) dhcp ports of the internal networks go from ACTIVE to BUILD
c) two type of errors are found on the neutron log file:
- a **Deadlock found when trying to get a lock** error, on one of the network nodes
- multiple **Duplicate entry ... for key PRIMARY** on both network nodes
How we replicated the issue

Some more information about our setup:
* 3 nova/glance/cinder/keystone servers, API endpoints balanced using HAProxy
* 3 MySQL Galera cluster, balanced using HAProxy, but in active/passive configuration (2 over 3 servers as backup in haproxy.cfg)
* 3 RabbitMQ cluster
* All nodes running Ubuntu Trusty and Kilo 2015.1.0 from `ubuntu-cloud.archive.canonical.com`
