I working on Kde Neon distro who based on ubuntu LTS version of 18.04.02 I notice that my operation system uses a lot of memory even when I not using the system at least one hour or even more it can take at least 5.6 or going to 7.5 GB in a hour.

Only when I open some programm the memory is dropped down to his natural using memory to 400-600mb.

I checked some proccess on top, htop, ps and I dont see anything who can take a lot of memory even when the all programms closed, the system is not in work couple of hours.

I tried to check it with Kwin, plasmadesktop,but they don't shows some notice or warnings to using high memory.

I fixed. It was about baloo indexing files in home directory page ./config/baloofilerc you to change from only basic indexing=true to false.

You just don't disable the proccess, you also need to check that the in the file you're basic indexing is not in true.

    Welcome to Ask Ubuntu. This site is for asking questions about Ubuntu and its official derivatives. So KDE Neon is considered off topic in this site. You might want to ask further questions regarding KDE Neon in the Unix and Linux Stack Exchange. Did you check which program is using such high memory? Open KSysGuard, go to process table, and list programs in terms of memory usage to find out. – Archisman Panigrahi Jul 10 at 18:49
  • askubuntu.com/help/on-topic I don't use KDE, but I've had systems go busy before when they are idle making thumbnails for directories that contain many thousands of photos which makes thunar more responsive when I actually use it, but Kubuntu (official flavor) is on-topic here, KDE-Neon is not – guiverc Jul 10 at 22:34
