@HenningAndersen I'm sorry to tag you in but I saw [this](https://discuss.elastic.co/t/g1gc-cause-circuitbreakingexception-parent-data-too-large-on-7-1-1/187272/33) thread which is similar to my issue. Here are my current custom JVM settings:

```
-Xms30g
-Xmx30g
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
10-:-XX:-UseConcMarkSweepGC
10-:-XX:-UseCMSInitiatingOccupancyOnly
10-:-XX:+UseG1GC
10-:-XX:InitiatingHeapOccupancyPercent=45
10-:-XX:G1ReservePercent=15
-XX:MaxGCPauseMillis=700
-XX:NewRatio=4
-XX:SurvivorRatio=6

```

Do you have any idea how can I stop this behavior?
