Hi ES team, We are getting this error from ES 7.4.1, querying an empty index (every 2s) on a server with no load (it's still in test mode so it's not receiving any request). We tried to increase the heap size from 2g to 4g, but no success. It's a one-node installation with CPU 32c RAM 128GB, HEAP SIZE 4GB (Linux Centos7, Zing JVM 1.8.0-zing\_19.12.100.0) The piece of code that returns this error is: ``` SearchRequest sr = new SearchRequest(this.pi.getIndexName()).source(new SearchSourceBuilder().query(QueryBuilders.matchAllQuery()).fetchSource(false).version(false)); SearchHit[] searchHits = cluster.getRestClient().search(sr, cluster.getRequestOptions()).getHits().getHits(); ``` The error is: ElasticsearchStatusException[Elasticsearch exception [type=circuit\_breaking\_exception, reason=[parent] Data too large, data for [\] would be [3110076554/2.8gb], which is larger than the limit of [3026295193/2.8gb], real usage: [3110076416/2.8gb], new bytes reserved: [138/138b], usages [request=0/0b, fielddata=0/0b, in\_flight\_requests=138/138b, accounting=0/0b]]] at org.elasticsearch.rest.BytesRestResponse.errorFromXContent(BytesRestResponse.java:177) at org.elasticsearch.client.RestHighLevelClient.parseEntity(RestHighLevelClient.java:1727) at org.elasticsearch.client.RestHighLevelClient.parseResponseException(RestHighLevelClient.java:1704) at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1467) at org.elasticsearch.client.RestHighLevelClient.performRequest(RestHighLevelClient.java:1424) at org.elasticsearch.client.RestHighLevelClient.performRequestAndParseEntity(RestHighLevelClient.java:1394) at org.elasticsearch.client.RestHighLevelClient.search(RestHighLevelClient.java:930) at com.ventusproxy.proxy.cluster.elasticsearch.CleanPercolator.run(CleanPercolator.java:49) at java.lang.Thread.run(Thread.java:748) Suppressed: org.elasticsearch.client.ResponseException: method [POST], host [[http://127.0.0.1:9200](http://127.0.0.1:9200)], URI [/pc\_102/\_search?typed\_keys=true&ignore\_unavailable=false&expand\_wildcards=open&allow\_no\_indices=true&ignore\_throttled=true&search\_type=query\_then\_fetch&batched\_reduce\_size=512&ccs\_minimize\_roundtrips=true], status line [HTTP/1.1 429 Too Many Requests] {"error":{"root\_cause":[{"type":"circuit\_breaking\_exception","reason":"[parent] Data too large, data for [\] would be [3110076554/2.8gb], which is larger than the limit of [3026295193/2.8gb], real usage: [3110076416/2.8gb], new bytes reserved: [138/138b], usages [request=0/0b, fielddata=0/0b, in\_flight\_requests=138/138b, accounting=0/0b]","bytes\_wanted":3110076554,"bytes\_limit":3026295193,"durability":"TRANSIENT"}],"type":"circuit\_breaking\_exception","reason":"[parent] Data too large, data for [\] would be [3110076554/2.8gb], which is larger than the limit of [3026295193/2.8gb], real usage: [3110076416/2.8gb], new bytes reserved: [138/138b], usages [request=0/0b, fielddata=0/0b, in\_flight\_requests=138/138b, accounting=0/0b]","bytes\_wanted":3110076554,"bytes\_limit":3026295193,"durability":"TRANSIENT"},"status":429} at org.elasticsearch.client.RestClient.convertResponse(RestClient.java:253) at org.elasticsearch.client.RestClient.performRequest(RestClient.java:231) at org.elasticsearch.client.RestClient.performRequest(RestClient.java:205) at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1454) ... 5 more .
