Last week, I indexed 1.2 TB data with one shard/zero replica on a single node, and ES worked fine. Later I tried to indexed the same amount of data with 24 shards on a node. But when my index size went to 480 GB (20GB in each shard), ElasticSearch crashed and the error message "There is insufficient memory for the Java Runtime Environment to continue" was thrown. After that, every time I tried to run ElasticSearch, it soon got crashed and the same error message appeared repeatedly. My ES\_HEAP\_SIZE is 64g (on a machine of 96 GB RAM). Supposed 480GB index size for 24 shards is not a huge number to ElasticSearch. So how come ES got OOM on this configuration? What should I do to get rid of this problem and have more than 100 shards on a single node as this thread [http://goo.gl/pAmKzb](http://goo.gl/pAmKzb) did?
