Likely glaciation, the bottom rock was likely on the bottom of an ice sheet and millions of tons of ice moving over it over time had smoothed it out.

The top rock is probably from many miles away and was carried and placed there from the receding glacier. To me the top rock looks like it is a completely different type of stone then the bottom.

You could write a simple bash script to get memory and compare it to your desired memory usage then clear memory when desired usage has been exceeded. Then set your script as a cronjob.

Or you can just setup a cronjob to clear memory at a set interval in a cronjob described in the link.
