Hi everyone,  
i have one node Elasticsearch:7.12.0 in docker with this configs:

```auto
environment:
    - bootstrap.memory_lock=true
    - "ES_JAVA_OPTS=-Xms31G -Xmx31G"
    - cluster.routing.allocation.disk.threshold_enabled=false

```

index rate is very high and it is about 15 milion documents for a daily index with120 GB size. each index have 6 primary shard and no replicas.  
we faced to this log with level WARN:

```auto
