I have 14gb allocated to elasticsearch v1.7.5.
Heap Used is at 11.7gb, I cannot find what is using up all this memory w/ the nodes/stats below.
Here are the memory related items I can identify, which account for ~4gb, leaving 7gb unaccounted.
Filter Cache Memory: 35mb
Field Data Memory: 20mb
Segment Memory: 2.7gb
Index Writer Max Memory: 1.4gb
Any ideas on how to identify what is taking up the heap space?
