Comment 11 for bug 1971451

SolQA got a similar case for openstack yoga/stable with juju 3.1, and memcache on latest/candidate(38, which is also latest/stable).
testrun: https://solutions.qa.canonical.com/testruns/44492416-057f-4468-956d-5b0817bec54a,
n-c-c is waiting memcache, but the memcached unit is active.

nova-cloud-controller/0 waiting idle 0/lxd/8 10.246.166.191 8774-8775/tcp Incomplete relations: memcache

in the logs I can see

Please let me know if I should file a new bug.
