------------------------------------

             Summary: Detect and fail explicitly on managed memory leaking
                 Key: FLINK-21799
                 URL: https://issues.apache.org/jira/browse/FLINK-21799
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
            Reporter: Xintong Song
             Fix For: 1.13.0


As discussed in FLINK-21419, it would be helpful to fail explicitly if a managed memory leaking is detected.

The leaking can be detected as:
* A segment being GC-ed is never freed.
* A memory manager being closed does not have all its memory released.
