从zmq.error.ZMQError中恢复:地址已在使用中 [英] Recovering from zmq.error.ZMQError: Address already in use

问题描述

与ZMQ运行PAIR模式(非阻塞客户端服务器)连接时，我按了Ctrl-C.稍后，当我尝试运行REQ-REP(阻止客户端单服务器连接)模式时，我总是收到Address already in use错误.我尝试用netstat -ltnp | grep :<my port>运行netstat，但是没有列出任何进程.

I hit Ctrl-C while running a PAIR pattern (non-blocking client servers) connection with ZMQ. Later when I tried running the REQ-REP (blocking client single server connection) pattern, I keep getting the Address already in use error. I have tried running netstat with netstat -ltnp | grep :<my port> but that does not list any process.

那到底是谁在使用这个地址?

So who exactly is using this address?

还有一个如何优雅地关闭此类套接字连接?

Also how does one gracefully shutdown socket connections like these?

推荐答案

问题1:

如果执行sudo netstat -ltnp，则在Linux类型的操作系统上，您很可能会看到拥有该端口的进程.用kill -9 <pid>杀死它.

If you do sudo netstat -ltnp, on a Linux type operating system, you will most probably see the process owning the port. Kill it with kill -9 <pid>.

问题2:

退出程序时，关闭套接字，然后调用zmq_ctx_destroy().这破坏了上下文.有关更多信息，请参见 http://zguide.zeromq.org/page:all#toc17

When you exit the program, close your sockets and then call zmq_ctx_destroy(). This destroys the context. See http://zguide.zeromq.org/page:all#toc17 for more info.
