使用http协议开启服务的时候，如果代码报错了，再重启服务就访问不了了，并且在关闭服务的时候报了一堆错误，请修复。

我用http协议开启了个服务，onMessage里面因为代码有问题报错了，然后重启该服务，在关闭该服务的时候会报错如下：

Warning: (null)(): supplied resource is not a valid stream resource in Unknown on line 0

我代码错误的地方在onMessage方法里面有一段代码，函数要求参数是引用类型，但是我传的不是，导致代码报错了。

重启了服务之后，http服务就访问不了了，是一直访问不了，必须把docker进程杀了才能好。
