> -------------------------------------------------------------------------------------------

> Key: HDDS-14856
> URL: https://issues.apache.org/jira/browse/HDDS-14856
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Priyesh K
> Assignee: Priyesh K
> Priority: Major
>
> HDDS-14800 fixed a TOCTOU race condition for the main volume iterator path by
> having {{ManagedRocksIterator}} hold the {{RocksDatabase}} reference counter
> for the full lifetime of the iterator. This prevents the DB from being
> physically destroyed while the iterator is in use.
> However, the fix only applies to iterators created through
> {{{}RocksDatabase.newIterator(){}}}. Several components bypass this layer and
> call {{ManagedRocksDB.get().newIterator()}} directly, so the counter is never
> acquired and the same race window exists for those iterators.
