Comment 5 for bug 1871332

There is something that seems off, because your logs is showing a traditional threading lock.
> Acquired lock <zone-id>

Can you make sure that the coordinator is returning a tooz based lock and not the lockutils based lock?

As an example you can look at the central logs from master. You don't see the lockutils used for zone actions here.
