Comment 16 for bug 1901898

This is definitely fixed by the advanced memcached pool setting in neutron server. For anyone new to kolla this is how to mitigate until Neutron is fixed.

1) Create/edit file /etc/kolla/config/neutron.conf
2) Add this to contents of the above file.
[keystone_authtoken]
memcache_use_advanced_pool = True
3) Run kolla-ansible -i inventory -t neutron --limit controller1,controller2,controller3 reconfigure
