memcache报错
这几天线上的memcache在频繁的报错，查了很多文章竟然都没有找到解决方法，最后终于找到了原因，以前也解决过，但是因为没有记录下来就又忘记解决方法了Mon Jun 09 11:54:55 CST 2014 - ++++ failed to close SockIO obj from deadPool
com.danga.MemCached.SockIOPool Mon Jun 09 11:54:55 CST 2014 - ++++ socket or its streams already null in trueClose call

最终的解决方法就是
/usr/local/bin/memcached -d -m 200 -u root -l 127.0.0.1 -p 11211 -c 2560 -P /tmp/memcached.pid
将-m和-c调大就ok了
