>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.5.3, 3.5.5

>            Priority: Major
>              Labels: pull-request-available
> {{ContainerManager}} does not delete containers whose cversion is zero to avoid situations
where a container would be deleted before the application had the chance to create children.
> This caused issues in our application where the process stopped between container creation
and child creation: the containers were never deleted.
> To avoid this while giving applications the time to create children, empty containers
with a cversion of zero should be deleted after a grace period, e.g. not when they are first
collected, but the second time.
