Bug: Erroneous Memusage
I have 2x8Gb's of ram on my desktop.
With that being said, I assume total memory usage should be lesser than 16Gb.
But ps_mem shows me some numbers above that range:
https://github.com/pixelb/ps_mem/assets/101834410/f3ceb976-2484-4a99-b1ea-57de41e7eb91
Can you provide the text output from ps_mem to give some indication of the potential over-counting. Also pertinent /proc/$pid/smaps_rollup files could be useful
I think I got the same behavior, total ps_mem ram usage is far superior to free ram usage:
