Our ElasticSearch version is v1.6.2.
31G jvm memory in 156G machine total memory.
Recently I found out our node is OOM frequently,then I found an index use "index_writer_memory" is so high.
It really confuse me,because this index is not a bigdata index,look below.
and at the memory flood out time,the index rate is not high at all.
Can anybody tell me whats going on and how can I fix this problem?
