we have es configuration like 3 master node(16GB, allocation 15 GB , hdd 2 TB) 3 data node (64GB, allocation 12 GB , hdd 2 TB) 2 coord node(32GB, allocation 15 GB , hdd 2 TB) Replica set to 2 . Data node have 2 TB data. 219 indices over all ( 657 shards) each index have 1 shard each When I am indexing I observed its reaching to max limit. I am not sure what is there in my memory , cluster stats says there are ~12k segments. 1. Is segments in memory that eating memory and causing circuit exception. segments: { - count: 12472, - memory\_in\_bytes: 25171110632, - terms\_memory\_in\_bytes: 22302468316, - stored\_fields\_memory\_in\_bytes: 2767848056, - term\_vectors\_memory\_in\_bytes: 0, - norms\_memory\_in\_bytes: 18428096, - points\_memory\_in\_bytes: 77911792, - doc\_values\_memory\_in\_bytes: 4454372, - index\_writer\_memory\_in\_bytes: 0, - version\_map\_memory\_in\_bytes: 0, - fixed\_bit\_set\_memory\_in\_bytes: 341385592, - max\_unsafe\_auto\_id\_timestamp: -1, - file\_sizes: { } 1. Heap dump shows some Class B(java.base@127.1.0) consuming 8GB memory and never flush off 2. Is it GC problem ? Any help appreciated. ---
