Hmz, seems like an error got inthere. Complete command is: /usr/sbin/mysql-proxy --proxy-address=:4040 --proxy-backend-addresses=127.0.0.1:3306 --proxy-read-only-backend-addresses=10.1.10.121:3306 --proxy-read-only-backend-addresses=127.0.0.1 --pid-fileroxy-lua-script=/usr/share/mysql-proxy/rw-splitting.lua
