Comment 3 for bug 1857114

nova is configured to use memcache as the caching backend in this job:

https://6081989ad82b8be7d120-53e9ef0ccb08d29c43f34421d87aa388.ssl.cf1.rackcdn.com/698632/3/check/networking-ovn-dsvm-grenade/72e94e8/logs/etc/nova/nova.conf.txt.gz

[cache]
memcache_servers = localhost:11211
backend = dogpile.cache.memcached
enabled = True

I see dogpile.cache==0.9.0 installed:

https://6081989ad82b8be7d120-53e9ef0ccb08d29c43f34421d87aa388.ssl.cf1.rackcdn.com/698632/3/check/networking-ovn-dsvm-grenade/72e94e8/logs/pip3-freeze.txt.gz

And I see memcached is installed:

ii memcached 1.5.6-0ubuntu1.2 amd64 high-performance memory object caching system

The errors drop off in recent days as well - was this fixed or worked around somehow?
