Please tell me what is the best way to clear the RAM, and how to check which process is using it? Recently, RAM has been gradually disappearing, I can’t understand what exactly such a large amount of RAM is being spent on.

kolu4iy : Well, I have most of the RAM in the cache, as I understand it, I shouldn't touch it? What if she gets all killed?

Check who eats memory - htop (more settings than in simple top)
kill the kill process, or reload it.

Spent on cache. Do not interfere with the operating system to work - it's supposed to. Don't forget to set smaller vm.swappiness in sysctl.conf, for example 10.
Look with atop - if the main amount of memory (MEM line) is indicated in the third column (cache) - then this is it. Do not touch.
If a particular process has eaten away, then all the previous tips are correct.
