screen shot of memory usage by app, showing Firefox using over 18GB of RAM

I also don’t understand why every chat app needs 1GB of RAM to itself.

      This site says Linux calls cached RAM “free” but in my screen shot it’s definitely being shown as “used”. I guess this is a choice of this app?

          Well top currently shows:

          While the “Mission Center” app shows:

            Subtract cached and free from total to get actual usage Htop shows visually though with cached as yellow or so I think you are using about 30 gb ram.

            Honestly, apart from firefox, what are you running? Does that include vms? I have 8GiB ram(7.1 usable) and uses like 1.8gb on idle and about 5-6.5gb on my personal highest usage

              No VMs. The RAM usage kept climbing until I was crashed out to the login screen and lost everything that was open. It seemed to be a particular website that gobbled RAM.

                  It sure does. I’ve never cracked 30GB RAM before. The site is doing something weird, for sure. Though I feel like Firefox should catch this before the OS crashes.

                    The OS crasching before Firefox seems weird. The OS should kill the offending process to free up memory for its own use. I wonder what went wrong.
