Andrey Zagrebin commented on FLINK-16313:
-----------------------------------------

Looks like native column ref leak inĀ  RocksDB. Possibly some column family 
object is not closed properly before closing RocksDB instance. If this started 
to happen recently but worked before, we should check any related latest 
changes.
