ESは時間の経過とともにヒープをゆっくりと埋め、14GBでハングしますが、最大のインデックスは164MBですか？
Elasticsearchに問題があります。14GB（最小および最大）に設定されたヒープサイズが完全に割り当てられていると言われているため、これを解放できないため、GCを継続的に実行しようとすることがあります。

この時点でESは応答しなくなり、再起動します
ESヒープを監視し、アプリケーションワーカーがESを使用すると、ヒープメモリが増大し、数分ごとにGCが実行され、ヒープはほぼ空になりますが、完全ではありません。そして、何日にもわたってゆっくりと、利用可能なヒープにメモリがないようです。 ESヒープについて話しているので、タイヤgemを使用したRubyコード）にメモリリークがあった場合を除いて、メモリリークが発生したように見えますか？ESの使用パターンによってはESがメモリリークになる可能性がありますか？ ？
基本的に、ESは16GBのRAM、レプリカなし、5つのインデックス、インデックスごとに1つのシャードを備えた専用サーバーです。 Java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el6_5.x86_64で実行され、mlockallを使用し、最小ヒープと最大ヒープの両方が14GBに設定されています。サーバー上では他に何も実行されません。開発チームはRubyワーカーで接続するために使用するタイヤの宝石を交換する余裕がないため、Elasticsearch 0.90.xを使用します

インデックスメタデータに何か問題がありますか？

6GBの最小/最大ヒープサイズを使用してみましたが、同じ動作を示し、すぐに応答しなくなります。
問題が解決しました：
DevはついにElasticsearchを1.3.2に更新することを許可し、Javaはこの時点で最新のOracleに変更され、RubyドライバーTireはsearchkickに置き換えられました（DevはAPIがTireと公式に近いと言ったため）ドライバーは複雑すぎて迅速な移行ができないようでした）。
デフォルト構成（-XminおよびXmaxなし）では、Elasticsearchは320MBを超えるヒープを使用せず、アプリケーションは以前と同様にウェイクアップしています。 XminとXmaxを2GBの静的な値に設定して、以前と同じメモリ使用パターンが表示されるかどうかを確認します。
