How are you determining what you call "consumed memory"?

Keep in mind that the kernel will by default use almost all free memory (not actually used by processes and libraries) as cache space, because it makes no sense to leave memory just laying around. However, once it's really needed, the caches will be dropped. Thus "free" memory is usually reported as low. Compare with "available" memory as reported by free.
