kibana内存溢出报错

1、ES-7.10.2 kibana-7.10.2

一：kibana页面打不开，查找kibana日志nohup.out文件

二、报错原因：

发现是前端 js 报的内存oom异常，通过网上资料发现node.js的默认内存大小为1.4G

Node中通过JavaScript使用内存时只能使用部分内存（64位系统下约为1.4G，32位系统下约为0.7G），这就是我们编译项目时为什么会出现内存泄漏了，因为前端项目如果非常的庞大，webpack编译时就会占用很多的资源，如果超过了V8对Node默认的内存限制大小就会出现node内存溢出的报错

CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

三、解决方案：

修改 --max-old-space-size 参数来调整内存大小的限制

1、进入kibana安装目录，编辑./bin/kibana

vim ./bin/kibana
NODE_OPTIONS="--max-old-space-size=4096"

编辑后如下：

注意：NODE_OPTIONS后面不能有空格

然后重新启动，观察日志
