Hi,

I have upgraded neutron server from victoria to wallaby. Everytime I
restart neutron server, I see below errors in neutron-server.log. Can you
guys please advise on it.

Secondly after upgrade, I can only see upgraded network agents in openstack
network agent list. The other agents that are on victoria release are not
showing up. Need your help.
