Currently, **\_nodes/stats** are in the state attached below.  
As it is, it is caught in the limit of Parent Ciruit Breaker, which causes a Circuit Break.  
I would like to know how to deal with this.

I am aware that the Parent Circuit Breaker is the total value of each breaker.  
Currently, the total value of request, fielddata, in\_flight\_requests, and accounting is 【about 7gb】. However, the "Parent Circuit Breaker" has a different value of 【15.1gb】.

What elements other than request, fielddata, in\_flight\_requests, and accounting are included in Parent's estimated\_size?  
And how can the other elements be checked?
