    Description

      The fuzzer uncovered an issue where the database was locked in global exclusive mode while the catalog was being modified. A concurrent thread performed UUID to namespace resolution, trying to query a collection, and got a NamespaceNotFound error because the UUID catalog was transiently empty. This situation should not have been observable because of the global exclusive lock.
