> Good day!

> Have I can see since this
> [commit|https://github.com/apache/flink/commit/6c44d93d0a9da725ef8b1ad2a94889f79321db73]
> TaskManager uses 8,388,607 terabytes as maximum out of heap memory. I guess
> that not any system has so much memory and it may be a reason to kill java
> process by OOM Killer.
>
> I suggest to decrease this value to reasonable value by default.
>
> Right now I see only one way to overstep this hardcoded value: setup
> FLINK_TM_HEAP to 0, and specified heap size by hand over
> FLINK_ENV_JAVA_OPTS_TM.
> Thanks
