This happened when connection was disconnected,but it would not happen every 
time,in common you can ignore this exception.

But i found that you stop the xmemcached client,so the client will try to close 
all connections now are connected,so it may throw this exception when closing.

If you found this exception when you stop the client,you can just ignore it.
