[GitHub] [incubator-brpc] yz-cyz opened a new issue, #1733: 网络断开自动重连问题
yz-cyz opened a new issue, #1733:
URL: https://github.com/apache/incubator-brpc/issues/1733
channel的两端网络突然中断后，client发送的request，持续报E1008，而没有重新连接
我们遇到的问题是网络中断后， 健康检查好像并没有生效，比如A -> B , 断网后很长一段时间内， A发给B的请求，还是会写入到socket的发送缓冲区（最少持续写入了10s以上）， 导致断网恢复时B突然收到大量请求。
看log， 10分钟后， 所有的请求还是会报E1008 超时错误， 而不是 E112 (Not connected to xxx)，
配置：health_check_interval = 3, health_check_timeout_ms = 500。
版本：0.9.7

@wwbmmm 那健康检查什么情况下才会重新连接呢，，我们这种情况，只要关闭连接重新创建连接就能避免， 但是业务侧没法重连。
怎么能够配置健康检查10s未收到答复就重连吗？

健康检查是基于连接的，这种情况应该是连接没有断开，brpc没有收到内核的通知，认为连接还是可用的，所以继续写数据，表现为超时。
