clearing the memory cache with a cron job cant hurt
Yes it can. There is no reason to clear the vm cache manually unless you are testing cache-related code paths. The kernel will automatically reclaim cache memory for program memory should the need arise, and uses the otherwise idle/free memory for disk cache. Clearing cache will only degrade the performance of your machine while the cached material is re-read from disk.
