基于此项目开发的平台和线下机器交互报错 mb_strlen() expects parameter 1 to be string, array given

[zhaobing45]

使用rageframe2框架加swoole开发的平台和线下机器交互，线下机器会向服务器推送数据。线下机器在每天会在夜里2点钟定时重启，重启之后就无法与服务器连接，报错 “mb_strlen() expects parameter 1 to be string, array given”，必须手动重启swoole。以下是错误日志：

经检查redis和swoole相关服务都是正常的

之前测试连接redis超时就会这样子
