Detailed Explanation
vm.min_free_kbytes is used to force the Linux VM to keep a minimum number of kilobytes free. if this value to lower than 1024KB, the system will become subtly broken, and prone to deadlock under high loads. Setting this value too high will OOM your machine instantly. vm.min_free_kbytes effect to the amount of available memory display output from the command $free -m. Linux Wolfman described how vm.min_free_kbytes impact to system.[1]
