Hi,

I'm running an ES cluster with 3 nodes using docker compose, my 3 nodes have the same below environment JAVA OPTS configuration. My understanding setting such value it would limit the memory usage, my node1 and 2 are rounding the 20 gb, it's ok, but my concern is why my node3 is exceding to 25 gb of usage.

```
environment:
  - bootstrap.memory_lock=true
  - "ES_JAVA_OPTS=-Xms20g -Xmx20g"

```

Example,

node3:  
 ![2020-01-28 11_05_20-root@sacvl1191__el1_app_elkstack_docker](https://us1.discourse-cdn.com/elastic/original/3X/4/c/4ced69fa3f7603750c6b255e0ab374dee0e86925.png)

node1 and 2:  
 ![node1](https://us1.discourse-cdn.com/elastic/original/3X/9/6/964f0885733f3c1e6a09752d6ca9a1d954c0cd2b.png)

Any help is very appreciable .

Regards,  
Jorge
