客户端使用v4.39.2或v4.40.0，grpc断开连接后无法自行恢复连接，必须手动重启客户端。 #1059

IRN-Kawakaze · 2021-06-09T15:25:33Z

你正在使用哪个版本的 V2Ray？

测试了以下组合：

服务端：v4.39.2，客户端：v4.39.2；

服务端：v4.38.3，客户端：v4.38.3；
服务端：v4.38.3，客户端：v4.39.2；
服务端：v4.38.3，客户端：v4.40.0；

服务端：v4.40.0，客户端：v4.38.3；
服务端：v4.40.0，客户端：v4.39.2；
服务端：v4.40.0，客户端：v4.40.0。

你的使用场景是什么？

服务端：nginx反代v2ray，开启tls，传输方式为grpc，传输协议为vmess（aead）。
客户端：使用chrome / firefox，利用v2rayN观看YouTube、GitHub和Google等网页。

你看到的异常现象是什么？

1、使用一段时间之后（几十分钟到半天不等），所有被代理的网页均无法打开。并且日志出现大量报错（具体报错内容见后文），重启客户端或重新选择节点后可以恢复正常。

2、经测试，在前面列出的多个组合当中，所有客户端为v4.39.2或v4.40.0 的组合，在使用过程中reboot服务器，可以100%复现该问题。
3、经测试，在前面列出的多个组合当中，所有客户端为v4.38.3 的组合均无法复现该问题（即该问题不存在或被解决）。
（使用这几个版本组合进行测试的原因参考这一issue：#1056 ，怀疑是同一原因所致）

你期待看到的正常表现是怎样的？

1、和其他传输方式或v4.38.3版本一致，能正常使用下去，不需要频繁手动重启客户端。
2、使用过程中reboot服务器之后，待服务器重启完毕，客户端可以自动恢复正常连接，不需要手动重启客户端。

请附上你的配置

测试了客户端v4.41.0 & 服务端v4.41.0和客户端v4.41.0 & 服务端v4.38.3，都正常，grpc可以自动恢复连接。

xiaokangwang · 2021-06-22T18:19:33Z

OK，非常感谢

It is important to use a detached context when creating shared transport connections that will outlive the initializing connection. Otherwise, once the original initializing connection is cancelled, the transport connection will be cancelled as well. This issue will be addressed in v5 by providing a transport session storage that also reduce the usage of globalDialerMap and other global variables.
