Description pd27@mail.ru 2023-08-04 02:29:45 UTC 
SUMMARY
I have 64GB RAM. After 4-5 days system uses around 60-70% of RAM. Killing plasmashell process and dropping cache frees 40-50% of RAM.


STEPS TO REPRODUCE
1. run PC
2. Wait 4-5 days.
3. plasmashell allocates around 40% of RAM. Whole system uses around 70%.
4. kill plasmashell.
5. sync; echo 3 > /proc/sys/vm/drop_caches free ~40% RAM.

OBSERVED RESULT
Every 4 days need killing plasmashell process, sync; echo 3 > /proc/sys/vm/drop_caches, runing plasmashell again for resume normal working.

EXPECTED RESULT
Working without killing plasmashell and erasing memory.

Are you using any 3rd-party widgets?

No.
Only widgets "from the box"? 3 stickers, 3 system info.
Comment 3 pd27@mail.ru 2023-08-05 16:00:10 UTC 
Previously I try to avoid this behavior by creating new user. It helped, but not so much, in helped for +-5 months.
Fresh user leaks memory around 8-9-10 days.
Comment 4 pd27@mail.ru 2023-08-05 16:02:23 UTC 
This happened from Leap 15.4.
In 15.3 I didn't have this. I could use system 1-2-3 months without reboot and hadn't leaks.
Comment 5 pd27@mail.ru 2023-08-05 16:18:36 UTC 
I know - plasmashell run a lot of processes.
How I can find out what exactly process leaks?
