不是什么假死，是客户端停掉了。

为啥

客户端主动停掉了，但是压侧还在继续跑，可能压侧代码写��
�有问题。

我跑的就是你提供的benchmark代码啊

我知道，所以我说可能写的有问题，有空我会看下。这个问��
�对你的压测结果没有影响，这个异常也是在这种场景下必须�
��出的。

恩，2个问题：
（1）这个异常也是在这种场景下必须抛出的？  什么场景下
（2）客户端主动停掉了？ 为什么会主动停掉？

（1）在MemcachedClient被stop之后，继续调用任何操作都应该抛出
MemcachedException，告知用户客户端已停止。
（2）这就是问题所在，benchmark的代码估计有问题，我会看下�
��

问题：客户端在什么情况下会主动停掉？？
