This stderr looks related (not sure why it prints to stderr instead of log4j

> usedNamespace is being decremented incorrectly
> ----------------------------------------------
>
> Key: HDDS-14435
> URL: https://issues.apache.org/jira/browse/HDDS-14435
> Project: Apache Ozone
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Wei-Chiu Chuang
> Assignee: Aswin Shakil
> Priority: Major
>
> [~sarvekshayr] reported that after HDDS-13756 seems to cause a regression:
> https://github.com/apache/ozone/pull/9115#discussion_r2685116012
> {noformat}
> After this PR, observed an issue where usedBytes is high while usedNamespace
> is 0, even though the bucket has no keys.
> It appears that usedNamespace is being decremented incorrectly. In the
> overwrite case, the namespace seems to be reduced twice, whereas it should
> done once by 1.
> Since the bucket has no data, this likely indicates a problem in how
> namespace is being updated during the commit or delete flow.
