> Key: OAK-3172
> URL: https://issues.apache.org/jira/browse/OAK-3172
> Project: Jackrabbit Oak
> Issue Type: Sub-task
> Components: segmentmk
> Reporter: Alex Parvulescu
> Assignee: Alex Parvulescu
> Labels: compaction, gc
>
> It looks like even if a component logs out a session, but keeps a reference
> to it around this will still prevent GC from running, as the session will
> wrap a _root_ reference pointing to the moment/revision when the session was
> last accessed.
