問題現象：

20台服務器有一台報monitor錯誤，查詢日志：

05 11 09:37:48 [MaintThread] ERROR memcached.SockIOPool - ++++ failed to close SockIO obj from deadPool
05 11 09:37:48 [MaintThread] ERROR memcached.SockIOPool - ++++ socket or its streams already null in trueClose call
java.io.IOException: ++++ socket or its streams already null in trueClose call

線上后端有類似的錯誤
