Yang Wang commented on FLINK-15906:
-----------------------------------
Even the taskmanager is killed by Yarn because of running beyond the limit, it
does not mean that we have memory leak here. Since the heap memory and direct
memory could be controlled by JVM. Maybe you do not set enough memory for
native memory. Firstly, i suggest you to increase the jvm-overhead enough to
make sure the taskmanager is not killed. Then use the native memory tracking[1]
to debug the memory usage. I think you should find something.

> Recently, we encoutered this issue when testing TPCDS query with 100g data.
> I first meet this issue when I only set the
> `taskmanager.memory.total-process.size` to `4g` with `-tm` option. Then I try
> to increase the jvmOverhead size with following arguments, but still failed.
