我正在运行 CentOS 6.2 服务器 1GB 内存 98GB 磁盘大小
Elasticsearch 版本 1.4.2，包含大约 9000 个文档，并使用 JDBC 从 mysql 数据库检索记录
在过去几周里，它平均每天崩溃 2 次。发生这种情况时，服务器无法访问，除非重新启动。（没有 ssh 访问权限，尝试访问网站时出现 500 错误等）
频繁重启 Elasticsearch 似乎可以防止服务器宕机，但我更愿意找到并修复问题的根源。以下是几天前发生的崩溃的日志：

每 60 秒将最后一行打印到日志中。
我已经尝试解决这个问题几个星期了。我是不是忽略了一些简单的事情，还是发生了一些更大的事情？
答案1
根据日志条目：
Unable to lock JVM memory (ENOMEM). This can result in part of the JVM being swapped out. Increase RLIMIT_MEMLOCK (ulimit).
除了升级 RAM 之外，你还需要更改 elasticsearch 配置这里
答案2
好吧，这条消息清楚地表明您遇到的问题是内存不足：
Oct 4 10:47:35 kernel: Out of memory: Kill process 1394 (java) score 107 or sacrifice child
或者限制 java/httpd 实例的内存大小。
