但是后面的Connection timed out(Read failed)中的(Read failed)不应该拼接在后面,因为其逻辑是kernel返回error就用kernel的error,否则用defaultDetail即(Read failed和errno的组合)。具体原因,笔者并没有在openJdk源码中找到,猜测可能是版本的原因或者oracleJdk和openJdk之间细微的差别。 ETIMEDOUT 既然是linux kernel返回...
查了下linux stderr手册,发现是ETIMEDOUT对应了Connection timed out。 但是后面的Connection timed out(Read failed)中的(Read failed)不应该拼接在后面,因为其逻辑是kernel返回error就用kernel的error,否则用defaultDetail即(Read failed和errno的组合)。具体原因,笔者并没有在openJdk源码中找到,猜测可能是版本的原因或...
最近在线上nginx经常出现输出connection timeout的日志,如下格式: 2016/03/17 15:33:01 [error] 32356#0: *102974264722 no live upstreams while connecting to upstream, client: 123.151.42.*, server: localhost, request: "POST /* HTTP/1.1", upstream: "http://geo_for_gdtbid/gdtbid", host: "*...

If a router functions as a client and the TCP connection is disconnected, the TCP connection is automatically re-established when data needs to be sent. Precautions If the RAW service has been enabled, run the undo raw-transport enable command to disable the RAW service before running the...
dev->tcp.signal_event = CreateEvent(NULL, // default security attributes FALSE, // manual-reset event FALSE, // initial state is nonsignaled NULL); 这个事件对象是手动重置并且不会发送初始状态信号。 初始IPv6网络的第一步是填充监听地址和端口,端口是由操作系统选择的,所以这里先将端口设置成0: ...
time_wait状态标准持续等待时间是4分钟,在这段时间内,小东和小升建立的 TCP 网络连接套接字资源(端口),是不能被其他人所使用的,也不能被系统回收重新利用的。 如果小升没有收到反馈,还会继续问下「重发 fin2 消息」,直到小东发送了 ack 消息成功了。双方正式关闭聊天通道,释放端口资源,连接关闭。
