YsoulM opened a new issue #8748: URL: https://github.com/apache/dubbo/issues/8748
- [] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. - [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.1 * Operating System version: centos 7.5 * Java version: 1.8 ### Steps to reproduce this issue 已经在搜索了issues，有人碰到类似的问题 #6404 由于线上已经使用，需要解决一下线上问题，我这边暂时提交了一个pull request。 https://github.com/apache/dubbo/pull/8746 能不能帮忙确认下，这样修改是否会有别的问题，谢谢。 ### Expected Result Provider停机后，Consumer中ReconnectTimerTask不再Reconnect ### Actual Result Provider停机后，Consumer中ReconnectTimerTask一直对已经销毁的Provider进行Reconnect If there is an exception, please attach the exception trace: ``` [DUBBO] Fail to connect to HeaderExchangeClient [channel=org.apache.dubbo.remoting.transport.netty4.NettyClient [/10.55.130.172:43584 -> /10.55.136.88:20880]], dubbo version: 3.0.1, current host: 10.55.130.172 org.apache.dubbo.remoting.RemotingException: client(url: dubbo://10.55.136.88:20880/cn.com.***.geo.api.remoteservice.RemoteIpAreaService?anyhost=true&application=geo-server&check=false&cluster=failfast&codec=dubbo&deprecated=false&dubbo=2.0.2&dynamic=true&generic=false&heartbeat=60000&interface=cn.com.***.geo.api.remoteservice.RemoteIpAreaService&isPerfTestSupportted=true&metadata-type=remote&methods=findAllIpInfoByIpIn,findIpInfo,findIpGeoInfo&release=3.0.1&retries=0&serverApplicationName=geo-server&side=provider&threadpool=cached&threads=500&timeout=3000&warmup=300000) failed to connect to server /10.55.136.88:20880, error message is:No route to host: /10.55.136.88:20880 at org.apache.dubbo.remoting.transport.netty4.NettyClient.doConnect(NettyClient.java:170) at org.apache.dubbo.remoting.transport.AbstractClient.connect(AbstractClient.java:197) at org.apache.dubbo.remoting.transport.AbstractClient.reconnect(AbstractClient.java:253) at org.apache.dubbo.remoting.exchange.support.header.HeaderExchangeClient.reconnect(HeaderExchangeClient.java:166) at org.apache.dubbo.remoting.exchange.support.header.ReconnectTimerTask.doTask(ReconnectTimerTask.java:49) at org.apache.dubbo.remoting.exchange.support.header.AbstractTimerTask.run(AbstractTimerTask.java:87) at org.apache.dubbo.common.timer.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:648) at org.apache.dubbo.common.timer.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:727) at org.apache.dubbo.common.timer.HashedWheelTimer$Worker.run(HashedWheelTimer.java:449) at java.lang.Thread.run(Thread.java:748) Caused by: io.netty.channel.AbstractChannel$AnnotatedNoRouteToHostException: No route to host: /10.55.136.88:20880 Caused by: java.net.NoRouteToHostException: No route to host at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) at io.netty.channel.socket.nio.NioSocketChannel.doFinishConnect(NioSocketChannel.java:330) at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe.finishConnect(AbstractNioChannel.java:334) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:702) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:650) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:576) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:493) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:989) at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.lang.Thread.run(Thread.java:748) ``` -- This is an automated message from the Apache Git Service.
