Cause of occurrence
`The crash occurred during the processing of _metric_entity at BaseTablet
destructor, from memory, the reference count for _metric_entity is already 0,
but there is still a weak reference, n a multithreaded environment, a race
condition may occur between deregister_entity and reset_metric_entity`
