我有一个脚本，它从csv文件中逐个读取行，并以相同的顺序将其索引到elasticsearch。我的elasticsearch主机与运行脚本的机器相同。当我突然开始出现以下错误时，除了几行之外，其他所有工作正常：

错误与csv中这些行的值无关。我在不同的时间在不同的位置得到这些错误。
还有一个错误“WAIT_TIMEOUT”我得到了一些时间。无法将跟踪放在这里，因为我这次没有收到错误。
我在ruby编码并使用“Tire”gem与elasticsearch交谈。我不认为这些是以任何方式负责的。
当我收到此错误时，JAVA使用了系统内存的8％。这远低于指定值ES_MIN_MEM = 2g。

这种情况正在发生，因为轮胎本身并未关闭tcp连接。一旦所有可用端口都被使用，在系统关闭处于等待状态的所有连接之前，不可能进一步连接。这需要一些时间，并且任何尝试建立新连接都会导致wait_timeout。
