我的服务启动后,会一直打印 changed ,但是我没有更新过这个配置文件,然后即使我通过 nacos web,重新编辑发布了这个配置,这个 changed 日志仍然会一直打印。磁盘空间基本都被打满了。是什么原因呢?

而且每条 changed 日志的 md5 值都是一样的。

客户端:
nacos-sdk-csharp.AspNetCore 1.3.8
nacos-sdk-csharp.Extensions.Configuration 1.3.8
服务端:
nacos/nacos-server 2.0.3

我理解,应该是服务端一直给客户端推送配置变化的通知,这两个服务内存占用率很高。我停掉客户端,服务器的内存占用率就降到基本为0%了。

贴一下 client 那边 nacos 相关的配置,我看前面的日志,用的还是长轮询。

服务端的 json 配置 qilun-auth-dev.json

不会是因为我服务端也配置了 NacosConfig 节点,起了冲突吧?

我不懂是不是bug,我客户端打包的时候,appsettings.json 添加了 "ClusterName": "DEFAULT", "GroupName": "DEFAULT_GROUP", ,重新发布之后,内存占用率变回0.x%了,然后我再去掉那两条配置,重新打包发布之后,也没有复现疯狂通知 changed 的现象了。这个现象不是必现,但是我遇到好几次了。不懂是什么原因恢复的。

这个问题还是会出现,不明白是什么原因导致一直认为 config 有变化,但是根本就没有改配置,客户端仍然会死循环一样接收到配置变化的通知。

我把nacos server 升级到2.4.2,似乎又好了。再观察观察后续还会不会出行这个问题。
