哈哈，可以用一下APR相关接口，或ZOMQ来写这个通信部分，移植方便，且不用管那么复杂的socket底层

当管道的读端关闭，写端继续写数据，会产生PIPE信号

检查一下是否管道读端异常关系

程序中忽略SIGPIPE信号
signal(SIGPIPE, SIG_IGN);

对已经收到RST的套接字进行写操作将导致 broken pipe,楼主的情况很可能是服务器被杀死这类的情况

Broken pipe一般是由于对方已关闭了接收的连接
检查一下socket连接吧

1，看看程序中是否有逻辑错误，导致误操作
2，write的时候读段是否处于关闭状态
3，其它情况
检查下程序吧

代码都没有，怎么查问题啊楼主

下面小编就为大家带来一篇完美解决Linux搭建sftp出现Write failed:Broken pipe的问题。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

socket连接时的异常解释及其产生原因 doc文档

在java网络编程Socket通信中，通常会遇到以下异常情况：　　第1个异常是 java.net.BindException:Address already in use: JVM_Bind。　　该异常发生在服务器端进行new ServerSocket(port)（port是一个0，65536的整型值）操作时。异常的原因是以为与port一样的一个端口已经被启动，并进行监听。此时用netstat -an命令，可以看到一个Listending状态的端口。只需要找一个没有被占用的端口能解决该问题了。　　第2个异常是java.net.ConnectException: Connection
