Hi, We are having a cluster running in Elastic search version 7.1.1 , details below.
1.) 4 node cluster where 3 nodes act as Data node and also is master-eligible and one node configured as coordinating only node.
2.) 16 GB of RAM, 10 GB allocated as Heap Memory.
3.) 3437652 docs & 89 GB of Storage Space used.
4:) It has 4 primary shards with 1 replica.
While indexing we are receiving the below error, i think this error happens when data is replicated across nodes using transport request but not sure why this is happening , as i am NOT seeing heap memory reaching 95% (which is default value for Parent circuit breaker as per ES docs - https://www.elastic.co/guide/en/elasticsearch/reference/current/circuit-breaker.html ) in this case. Can somebody help us on this to understand more & fix this issue ? Thanks and appreciate your help.
