    Description

      There is a path where a system.buckets collection can be orphaned if a previously created collection shares the namespace of a proposed createCollection with timeseries options. This bug can likely be addressed in the createCollection path for timeseries where a system.buckets collection is created prior to any namespace checking for existing collections.
