security vulnerabilities before their coordinated publication by the

associated fixes in public forums such as mailing lists, code review
systems and bug trackers. Please also avoid private disclosure to

It would appear Nova is revealing information that may be sensitive in
error messages

infra/2019-July/006426.html
I attempted to hard-reboot it, and it went into an error state. The
initial error in the server status was
{'message': 'Timed out during operation: cannot acquire state change
lock (held by monitor=remoteDispatchDomainCreateWithFlags)', 'code':
500, 'created': '2019-07-25T07:25:25Z'}
After a short period, I tried again and got a different error state
{'message': "internal error: process exited while connecting to
monitor:
lc=,keyid=masterKey0,iv=jHURYcYDkXqGBu4pC24bew==,format=base64 -drive
'file=rbd:volumes/volume-
41553c15-6b12-4137-a318-7caf6a9eb44c:id=cinder:auth_supported=cephx\\;none:mon_host=172.24.0.56\\:6789",
'code': 500, 'created': '2019-07-25T07:27:21Z'}
I don't know if this is a setting or a bug. Better to report and close
than not say anything I guess.
