Github user aljoscha commented on the pull request: https://github.com/apache/flink/pull/1433#issuecomment-162846459 I also discovered some other stuff, for example, the off-heap memory usage is not printed by the `MemoryLogger` (max is fixing this) and some stats in the web fronted about TaskManagers are wrong. For example "Free Memory" is simply the size of the JVM Heap.
