关于在msgagent挂起的task

[ericzhanchina]

在msgagent弄了三个response形式的响应，比如客户端请求怪物刷新的信息，我这里先挂起，然后等有了刷新再回复给客户端，这样我发现会在gated和msgagent挂起很多的任务，然后按理说我三个协议采用了response，那么应该只有三个任务挂起吧，今天看控制台，具有的msgagent居然有11个挂起，但是有些是table，我看不了。想请教大家，这种设计方式有没有问题，要不要改成轮训的方式。第二，这个msgagent怎么会有这么多的session没有回复给客户端呢？怎么会造成这样的情况。

是否可能因为没有回复，又有新的请求又挂起

[ericzhanchina]

不知道，正常的那些挂起都是能看到代码的，但是像13178 13177这样的session啥都没有，也不知道啥挂起来了
