If you raise the min_free_kbytes to 8192 you should not see the memory drop below 8kbytes when you run the command free.

root@zeroshell root> free
total used free shared buffers cached
Mem: 188528 171812 16716 0 38340 34652
-/+ buffers/cache: 98820 89708
Swap: 131064 0 131064

For example here, when the 16716 drop below 8192, the system will free some memory used in buffers and cache to allocate in the programs that need it. If you see less than 8kbytes memory in your ZS then something else is wrong. I think it is unnecessary to run a cronjob for freeing up memory.
