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.
Are you by chance using an integrated GPU?
Noticed that my AMD Radeon 680M uses quite a lot of RAM as shared memory.
Using something like
amdgpu_topwill show how much RAM your iGPU is using, metric is ‘GTT’No integrated GPU.
If you had something hog memory and a lot of other stuff got paged out of ram as a result, that can slow things down. Try running “top” and see how much swap space is in use. If it’s more than a little bit, once you have enough memory available by shutting off whatever was hogging it, try “swapoff” (pages the stuff back in, which can take a little while) followed by “swapon” to re-enable swap.
Check if there’s any large file in /tmp and /run/user/*?
No large files.
Probably this but seems like a pain to use:

Do you use ZFS? It uses half your RAM for cache by default, which matches with 2GB used by user apps + 16GB = 18GB total.
Stop using Newsflash or submit a bug report?
I’m not sure if it is related to Newsflash is the problem. Besides, I’ve been using the same version for months, but this has only recently become a problem. And the problem persists after Newsflash is closed.
Got it, but it seems like Newsflash may have a memory leak issue?
To my understanding, the kernel should clean up any memory leaks an app has when you close it.

echo 3 | sudo touch /proc/sys/vm/drop_cacheschange the available RAM at all when this happens?deleted by creator
