You're probably at the limits of what you can do with that many nodes then. You may want to look at reducing the shard count too, that's only ~4GB a shard, which is very small. ---

too big shard will create other problems ? ---

Less than 50GB. Are all your shards an even size? Do you have some really small ones with hardly any data, and then some that are really larger? ---

Increase shard size,but don't solve this problem, only reduce 5% memory in use。 I want to know content in terms\_memory, when and how it's generated，it's can LRU? [Next page](https://discuss.elastic.co/t/how-to-reduce-terms-memory-in-bytes-help-help-help/49135.md?page=2)
