Xintong Song commented on FLINK-15906:
--------------------------------------
The exception suggests that the task manager is consuming more memory than
expected.
A java program may consume various types of memory: heap, direct, native,
metaspace. For all the types, except for native memory, Flink sets explicit
upper limits via JVM parameters, so that an `OutOfMemoryError` will be thrown
if the process tries to use more memory than the limit. Since there's no OOM
thrown, the only possibility is that Flink uses more native memory than it
planned.
Increasing JVM overhead, Flink will reserve more native memory in the
container. The extra memory may not be actually used by JVM as its overhead,
but should help with your problem.
BTW, did it solves your problem?

> Recently, we encoutered this issue when testing TPCDS query with 100g data.
> I first meet this issue when I only set the
