Hi, please help.  
Do exist test case which are used curl and /nodes/stats response  
for issue  
[Ensure that releasing listener is called](https://github.com/elastic/elasticsearch/pull/23310#issue-209518352) ?  
I have exception

```auto
Caused by: org.elasticsearch.common.breaker.CircuitBreakingException: [parent] Data too large, data for [<transport_request>] would be larger than limit of [4442554368/4.1gb]

```

and I would like detect rootcause of this exception before elasticsearch upgrade.  
Also can you please explain the difference between  
limit\_size and estimated\_size fields? I could not find it in documentation

```auto

        "request" : {
          "limit_size_in_bytes" : 3807903744,
          "limit_size" : "3.5gb",
          "estimated_size_in_bytes" : 4442546784,
          "estimated_size" : "4.1gb",
          "overhead" : 1.0,
          "tripped" : 92
        },
        "fielddata" : {
          "limit_size_in_bytes" : 3807903744,
          "limit_size" : "3.5gb",
          "estimated_size_in_bytes" : 0,
          "estimated_size" : "0b",
          "overhead" : 1.03,

        },
        "in_flight_requests" : {

          "limit_size" : "4.1gb",
          "estimated_size_in_bytes" : 4442547281,
