Connection reset by peer
NettyChannelHandler exceptionCaught: remote=/:58400 local=/:**** event=java.io.IOException: Connection reset by peer 或者Connection timed out
服务总是报这个错误 timed out 是不是check的时候没有链接上 我把防火墙关了就报Connection reset by peer
估计是跟网络有关，可以确认一下server注册时自动获取的ip是否正确，有无配置虚拟网卡，或者直接使用telnet在client端直连一下试试看网络是否正常 另外可以确认一下是完全无法建立链接，还是定期出现这样的异常？如果是偶发异常client端调用应该是可以成功的
１、注册时是没有问题的 ２、也没有配置虚拟网 ３、直接链接是可以链接的上的
Connection timed out 这个应该是“检查服务提供者是否存在”时 使用了随机端口 client和server在不同的机器 这个随机端口没有开放 但是Connection reset by peer就不知道是什么原因了 是不是连接数太多了？ @rayzhang0603
client端只会链接server端在注册中心注册的端口，Connection timed out这个异常应该是client端与server端建立链接时发生的吧？可以配置一下connectTimeout试试，默认是1s Connection reset by peer一般来讲是对端关闭了链接，可以确认一下client端有没有关闭链接的记录。如果网络状况不好，可以把requestTimeout调大一些试试。
我看报错信息里面remote=/ip:58400 local=/ip:port local是没问题的 remote的端口一直在变
client也没有关闭链接的记录 差不多20-30分钟报错一次
@rayzhang0603
Connection reset by peer应该是client已经断开的链接，server端仍有写入，可以在client端debug一下netty，看看链接的建立与关闭有没有什么可疑的地方吧。偶发下这种情况对client端的请求应该不会造成影响
以前一直没有问题，最近几天服务器都在报这个错，怀疑是阿里云的工程师调整了某个网络参数导致的，业务使用正常没发现有丢消息的情况，但是每个几十分钟就会有这个报错 @srmsh 请问问题是否已解决了呢？谢谢。
问题解决了吗？我也遇到这种问题了，间隔一分钟就报错。 2018-08-12 22:27:19.346 ERROR [New I/O server worker #1-4]error 87 error - NettyChannelHandler exceptionCaught: remote=/172.31.178.85:35262 local=/172.31.178.82:15601 event=java.io.IOException: Connection reset by peer java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcherImpl.read0(Native Method) ~[?:1.8.0_111] at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) ~[?:1.8.0_111] at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) ~[?:1.8.0_111] at sun.nio.ch.IOUtil.read(IOUtil.java:192) ~[?:1.8.0_111] at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:380) ~[?:1.8.0_111] at org.jboss.netty.channel.socket.nio.NioWorker.read(NioWorker.java:321) ~[netty-3.2.5.Final.jar:?] at org.jboss.netty.channel.socket.nio.NioWorker.processSelectedKeys(NioWorker.java:280) ~[netty-3.2.5.Final.jar:?] at org.jboss.netty.channel.socket.nio.NioWorker.run(NioWorker.java:200) ~[netty-3.2.5.Final.jar:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [?:1.8.0_111] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [?:1.8.0_111] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_111]

赐教啊，这个问题有没有什么好的解决方案啊？ An exception '{}' [enable DEBUG level for full stacktrace] was thrown by a user handler's exceptionCaught() method while handling the following exception: java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcherImpl.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) at sun.nio.ch.IOUtil.read(IOUtil.java:192) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:380)
@srmsh @ @rayzhang0603 @lytofb @ @lihaipeng0417 @ivancxj 请问有了解决方案了吗？ 我的也是一直出现这种问题，求解！
