I'm not sure how it works internally but may be corona uses as much ram as possible to store lightning solution, textures, rendered passes,... whatever, and avoid swapping/hd access as much as possible along rendering...
You can see many people rendering vegetations, I did it too over 12Gb ram covering 40.000m² grass (6 variety) with +- 50 trees (6variety), and it worked good.
The question is have you some memory issue impacting your rendering ? If not why by hell should you preserve ram from being used while you paid for it to be full and fast :)
Although if you want to render while doing something else a ram limitation setting would be usefull.
PS : you can eventually check with the corona benchmark interior scene, your interior might be simple, if you subdiv a pillow till 30Mpolys it would still eats ram like a mad shark... may be some object got corrupted in that way ?
