ERROR swFactoryProcess_finish (ERROR 1004): send 1954 byte failed, because session#3 is closed.

centos 6.5, php5.4, swoole 1.8.7

tcp server中 程序通过socket 同步连接别的服务读取数据
对fd进行各种读取操作，非常大概率出现
ERROR   swFactoryProcess_finish (ERROR 1004): send 1954 byte failed, because session#3 is closed. 类型错误
同样的代码运行在Http server下没有此类错误
