xxl执行节点错误日志刷屏

我使用阿里云服务器搭建了xxl的执行节点，但是一直在刷屏错误日志

2021-06-23 20:59:54.015 [ERROR] 1 --- [ntLoopGroup-3-7] j.c.s.EmbedServer$EmbedHttpServerHandler : >>>>>>>>>>> xxl-job provider netty_http server caught exception

一开始是以为xxl引用netty版本冲突，因为redis里面也引用了netty，后来强制引用一致的netty版本，发现还是不能解决，最终找到了问题：我们使用的是阿里云搭建的服务，也是用阿里云的slb开通服务访问，负载均衡默认会开启安全检查，就是不断的去ping你的接口，这样调一次报一次错，所以只需要把你的负载均衡安全检查关闭就好了

如下图，把执行节点监听的端口的健康检查关闭掉就解决了
