I've found it! The problem not caused by pynetdicom but `pydicom0.9.9`. The `DicomFileLike`'s superclass `DicomIO` has defined the method `__del__` and it has 5 method referenced itself, so it's reference-cycle....
Issue raised at [DicomFileLike object caused memory leak #371](https://github.com/pydicom/pydicom/issues/371)
And mine is no leak too.
The bug in pydicom has been fixed.
This issue still persists on v2.0.69
any update here?
