我在Ubuntu 14.10上使用Elasticsearch，它会周期性地closures（进入失败状态）。 停机时，会在我的网站上抛出exception，用户无法正确search，连接或更新数据库。
当我得到服务的状态，如果运行，我有：
elasticsearch.service - ElasticSearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled) Active: active (running) since Wed 2015-04-15 15:47:39 CEST; 8min ago Main PID: 253 (java) CGroup: /system.slice/elasticsearch.service └─253 /usr/bin/java -Xms256m -Xmx1g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFr... 我已经configurationsystemd总是重新启动服务，如果下来，它的工作，但仍然，它每隔一小时左右。
我怎样才能找出原因呢？
EDIT1：我在var / logs / elasticsearch中发现了一些elasticsearch日志文件。 我有一个重复的元素：

不知道这是关于这一点，但我想通过java 1.7u55赌注弹性search效果最好： https ://www.elastic.co/blog/java-1-7u55-safe-use-elasticsearch-lucene
