Question [Q]how to get the lowmemorykiller working?

i flash the GBRider_Cronos_v1.5.0 Rom

change the file system/etc/init.d/30tweaks the last two line

“echo "1536,2048,4096,5120,5632,6144" > /sys/module/lowmemorykiller/parameters/minfree”

into

“echo "1536,3072,4096,21000,23000,25000" > /sys/module/lowmemorykiller/parameters/minfree”

then i used ADB

“cat /sys/module/lowmemorykiller/parameters/minfree”

output for this

“1536,2048,4096,9216,10240,10240”

seems to be the num i changed doesn't work
