Hello there, We are having the same exact problem with a really resource hungry query: 5 nodes with 16GB ES_HEAP_SIZE 1.2 Billion records inside 1 index with 5 shards
Whenever we start running an aggregate query the whole cluster breaks and disconnects. Why can't it just not return results and simple give and error without actually killing the entire cluster?
