我这启动了一个 java 的 provider， 3 个 zk 做注册中心， go client 用 100w 次 loop 请求，内存变化不是很大。你这边有最小复现流程么？

您这边是测试的代码么？如果是的话，可以试试，在 subscribe 那边加一个return，比如 失败 2 次就 return，先不 DoSub, 看看内存情况。 可以先下一个 dubbo-go 然后 用 go mod edit 去替换掉dubbo-go。
我还在找root cause。

平常状态下比较难复现，你也是 go 调用 java 么？

如果可以的话，发一下内存的增长的截图。如果有条件的发下 内存 diff profile的log
```
curl -s http://127.0.0.1:8080/debug/pprof/heap > 1231.heap
过 一段时间 (5m, 10m, 30m, 1h)
curl -s http://127.0.0.1:8080/debug/pprof/heap > 1241.heap
go tool pprof --http :9090 --base 1231.heap 1241.heap
```
