Just a tip in future, if Centmin Mod latest updated code doesn't have the newer version defined in /usr/local/src/centminmod/centmin.sh, you can override it yourself via persistent config file /etc/centminmod/custom_config.inc variable set as:

Code (Text):

MEMCACHED_VERSION='1.5.2'

then run centmin.sh menu option 10. Just remember you'd have to edit MEMCACHED_VERSION in /etc/centminmod/custom_config.inc or remove it for future updates too otherwise centmin.sh menu option 10 runs will be stuck on whichever version you set for MEMCACHED_VERSION in /etc/centminmod/custom_config.inc
