I've been running into an issue recently where my system will start to stutter and freeze. Going into my task manager (Resources), I can see my using is using roughly 18/32GB of RAM despite closing all apps. Normally I should be at around 2GB on a fresh boot.
I've only noticed this issue appearing when first interacting with an app called Newsflash, but the issue persists even after closing the app. I even tried using systemd's soft-reboot feature and even that did not clear the memory leak. So it seems the memory leak must be in the kernel itself.
And please don't link linuxatemyram. This is not related to cached data.
I don't know what this tool is or how it gets its "memory" metric. If you want to continue to use it, please ascertain that these values correspond to RSS by cross checking with i.e.
ps aux. RSS is the memory exclusively held by a given process which is typically what mean by the "memory usage" of any given process. Note however that this does not count anonymous pages of a process that are swapped or shared with other processes.This does not tell you (or us for that matter) anything without defining what "using" means here. My system is "using" 77% of RAM right now but 45% of memory is available for use because it's cached.
Please post the output of
free -haswell asswapon.Next, please post the contents of
/proc/meminfo.Do you use ZFS?
Resources reports the same memory usage as btop. free tells me only 6GB is being used for cache.
On a fresh boot, Resources and btop report less than 2GB RAM usage, obviously not including cached stuff. So for both tools to report 18GB with no apps open, it’s strange.
ps aux looks all normal, nothing in the background using more than 1% of RAM.

If you're not going to post what I asked for, nobody can help you.
