最近在学习`Dubbo`源码，当学习到`Dubbo`中有关`EagerThreadPool`相关知识时遇到了一个问题，下面是我的`dubbo-demo`的一些配置：

   然后我使用`Jmeter`进行压测，模拟高并发场景

   紧接着，使用 `jmeter -n -t`命令执行压测
   
   在这个过程中，会出现 `Dubbo`线程池耗尽的警告信息

   ```
   
   
   
   本来也很正常，`Jmeter`文件里设置了线程数为 100

   但是报错信息的 
`Pool`的`activeCount`竟然不是**10**，**如果线程池耗尽的话**，**这里的activeCount应该是10**才对。

   这是为什么？
