Hi Team, I am using elasticsearch 7.7.1. I have 3 data nodes(31GB) and 3 master nodes(16GB). With a heavy load, I am getting below error and I can not see my data node on the monitoring tool for 10-15 mins, also at that particular time, Search is not working. After 10-15 mins, I can see all data nodes on the monitoring tool. ``` Data too large, data for [] would be [16329231844/15.2gb], which is larger than the limit of [16320875724/15.1gb], real usage: [16329230592/15.2gb], new bytes reserved: [1252/1.2kb], usages [request=0/0b, fielddata=0/0b, in_flight_requests=1252/1.2kb, accounting=0/0b] at org.elasticsearch.indices.breaker.HierarchyCircuitBreakerService.checkParentLimit(HierarchyCircuitBreakerService.java:347) ~[na:na] at org.elasticsearch.common.breaker.ChildMemoryCircuitBreaker.addEstimateBytesAndMaybeBreak(ChildMemoryCircuitBreaker.java:128) ~[na:na] at org.elasticsearch.transport.InboundHandler.handleRequest(InboundHandler.java:171) ~[na:na] at org.elasticsearch.transport.InboundHandler.messageReceived(InboundHandler.java:119) ~[na:na] at org.elasticsearch.transport.InboundHandler.inboundMessage(InboundHandler.java:103) ~[na:na] at org.elasticsearch.transport.TcpTransport.inboundMessage(TcpTransport.java:676) ~[na:na] at org.elasticsearch.transport.netty4.Netty4MessageChannelHandler.channelRead(Netty4MessageChannelHandler.java:62) ~[na:na] ``` For that time, my Search is not working. Can you help me with that? Other relevant modifications to my jvm.option file ``` 8-13:-XX:+UseG1GC 8-13:-XX:G1ReservePercent=15 8-13:-XX:InitiatingHeapOccupancyPercent=40 8-13:-XX:MaxGCPauseMillis=400 8-13:-XX:ConcGCThreads=4 8-13:-XX:+ParallelRefProcEnabled 8-13:-XX:+UseTLAB 8-13:-XX:+UseStringDeduplication 8-13:-Xlog:gc*=info:file=gc.log:time,tags:filecount=100,filesize=1024k ``` Other relevant modifications to my elasticsearch.yml file ``` node.master: true node.data: false node.ingest: false bootstrap.system_call_filter: false xpack.ml.enabled: false node.transform: false node.ml: false xpack.transform.enabled: false node.remote_cluster_client: false discovery.seed_providers: file thread_pool.write.size: 16 thread_pool.write.queue_size: 8000 ``` Other stats : Total Indices: 63 2 Primary Shards, 1 Replica Total Size: 61 GB We have changed below cluster-level settings. ``` "refresh_interval": "15s" "search.idle.after" : "10000d" ``` Can anyone suggest what is wrong here?

What is the output from `hot_threads` during that time? ---
