I have set the memcached_servers flag in nova.conf:
memcached_servers=192.168.220.41:11211,192.168.220.42:11211,192.168.220.43:11211
I receive the same error even when I front-end the memcached servers
using a load-balancer vitual IP:
memcached_servers=192.168.220.40:11211
I have yet to test, but I recall seeing a similar problem in Folsom
with consoleauth/manager.py
