I still see this every 3 seconds:

Any chance you would know what in openflow is causing this? I know I can stop it by doing this [1], but that is not ideal.

Thanks,

Steps to reproduce:

using master, karaf distribution

  1. start ODL
    feature:install odl-ovsdb-openstack
  1. stack on openstack (single node [2] is fine)

source openrc admin admin
neutron net-create net1 --tenant-id $(keystone tenant-list | grep '\s'admin'' | awk '

{print $2}') --provider:network_type gre --provider:segmentation_id 555
neutron subnet-create --tenant-id $(keystone tenant-list | grep '\s'admin'' | awk '{print $2}

') net1 192.168.10.0/24 --name subnet1 --dns-nameserver 8.8.8.8
neutron router-create demorouter --tenant-id $(keystone tenant-list | grep '\s'admin'' | awk '

{print $2}

')
neutron router-interface-add demorouter subnet1

Comment by Flavio Fernandes [ 21/Apr/15 ]

We now work around this bug by using different priorities for rules
that only differ in the extension portion of the match.

The real issue is now being tracked via OPNFLWPLUG-402.
