EDAS 应用开启健康检查后应用一直报503 ，NacosException: failed to req API:/api//nacos/v1/ns/service/list #2001

Open lidaoyang opened 3 years ago

sca version: 2.2.1 according to the following log, it is always called after health check is enabled, NamingProxy.getServiceList(), causing the server-side throttling to be triggered. Check whether the health check on config maintains a variable. Can this be changed to a similar method?

sca版本：2.2.1 根据下面日志发现开启健康检查后会一直调用，NamingProxy.getServiceList()，导致触发server端限流。查看了config那边的健康检查是维持一个变量。这个是否可以改成类似的方式？ image
