the reference check time needs to exceed 1s, because the default value of reconnectTaskPeriod is 1000 which means connectivityExecutor might wait 1s to recover the invoker from invalid list, otherwise reference checking might get failure result just like this: ``` 18:21:41.131 |-INFO [NettyClientWorker-4-2] .transport.netty4.NettyConnectionHandler:95 -| [DUBBO] The connection [id: 0xbb84b379, L:/172.18.0.4:34928 - R:/172.18.0.3:50051] of 172.18.0.4:34928 -> 172.18.0.3:50051 is established., dubbo version: 3.3.6-SNAPSHOT, current host: 172.18.0.4 18:21:42.124 |-WARN [main] org.apache.dubbo.config.ReferenceConfig: -| [DUBBO] Check reference of [org.apache.dubbo.samples.api.GreetingsService] failed very beginning.
