Hello. I would like to ask question about the heap memory. I am trying to free up heap memory by closing old indices. When I look at the chart of heap usage there is always some left overs after each _old gc_ . In below example about _8.0 gb_ is remained after each gc. ![gc](https://us1.discourse-cdn.com/elastic/original/3X/1/6/16e89bdc76251be9b40491046e528b9418a3ea82.PNG) By looking at _Terms_ in _Index memory_ chart , there seems to be no change in the trend event though gc occurs. So I thought _Terms_ remains after each gc therefore I thought I could free more heap memory by closing the index which means I am freeing _Terms_ area of each index. ![index_memory](https://us1.discourse-cdn.com/elastic/original/3X/4/a/4a2dd2adc4496cb784ee7867b9ad5888fc15cc13.PNG) Is _Terms_ one of the area which remains after the GC ? I appreciate if I could get some help with my question. Best Regards, Yu Watanabe ---
