My computer over the last week has (after using the computer for a few hours) shown very high ram usage, around 50 - 60% out of 32GB, even though nothing in htop appears to be the culprit with the highest consumer being Firefox at 1.6% ram, even in a tty, around half of my ram is being used up even though no process shows over 0.1% ram. Rebooting does seem to work, but I'd prefer not to every few hours. Do you think it might be an issue with hardware? I did build my pc so perhaps something's broken?

        Run free -m and look at the output. That will tell you how much memory is used by programs, how much is being used as cache, and how much is available. The memory used as cache will be freed if a program needs it.

            Something's using a lot of memory. It's not just buffer/cache memory. That's definitely not normal.

            Did it just recently start using that much memory? I would suspect that something has a memory leak.

    Could you create a pie graph using smem?

    Are you using ZFS?

    If you close firefox, how much RAM is used?
