i think the data growth
so the jvm is too small
only 300m
as i know, 31G is better about per node.

Not really. It depends on the data you have and what you are doing.
I've seen lot of clusters with 4gb of HEAP.
I'm running locally a demo with 1Gb HEAP for 1 million documents.
So it depends...

Probably too many indices or data?
What is the output of:
```auto
GET _cat/nodes?v
GET _cat/indices?v
```

Apparently you opened another thread about this at [My kibana has nothing but i think is elasticsearch problem](https://discuss.elastic.co/t/my-kibana-has-nothing-but-i-think-is-elasticsearch-problem/140661/8)
Please keep the discussion in one single place instead.

That's probably perfect for your use case but you can not recommend that as a general advice. That can mislead the other users IMO.
