Ram keeps going up and never goes down.

[simrsta]

I have several containers containing applications that I use.

Initially, I used 16GB of RAM, but why does RAM usage keep increasing every day?

Until it's full and my applications are loading, but if I stop and restart the CT, the RAM usage starts all over again?

Shouldn't RAM usage decrease when no one is using the application?

It's like it's stuck.

Yes and... no, not to the same low level as at the beginning.

Unused RAM is wasted RAM - it will be used for caching purposes for example.

No, never. Your shelf in the cellar, that is filled with stuff, is also not automatically available if no one is using it.

As with the shelf in the cellar, if you want to store something new, something old has to go away. This is only done in the moment it is required. If you close an app, the memory is only marked as clear, but actually it is not. This is also true for files on your disk. They're only marked as deleted and can be overwritten. Unless they are, they can be undeleted.
