> Project: Flink
> Issue Type: Improvement

> We observed a difference between the configured maximum heap and the maximum
> heap returned by the metric system. This is caused by the used garbage
> collection (see [this
> blogpost|https://plumbr.io/blog/memory-leaks/less-memory-than-xmx] for
> further details).
> We should make the user aware of this in the documentation mentioning it in
> the memory configuration and the metrics page.
