关于swoole_client同步模式在php-fpm模式下websocket_server不稳定问题

我想实现类似图中的功能。就是通过浏览器A 用http post方式发送给我的业务代码接口中，然后在业务代码接口中用swoole_client同步阻塞的方式发送给websocket_server端，由websocket_server把消息发送给 浏览器B。

![](http://www.workerman.net/img/doc/work-with-other-mvc-framework.png)

浏览器执行包含swoole_client方法的文件，有时以后能走websocket_server中的onMessage方法，有时候不走，导致不能发送消息给浏览器B。大部分情况下是失败的。

命令行执行包含swoole_client方法的文件，有时以后能走websocket_server中的onMessage方法，有时候不走，导致不能发送消息给浏览器B。少部分情况下是失败的（基本上都成功，但也有的时候失败）。

不知道什么原因，有哪位大神走过这条路，麻烦指点一下，我应该错在哪里，为什么有的时候能成功，有的时候会失败。

代码如下：
服务端websocket_server代码（运行在CLI模式下）：
{{{
