@oldsysops @unfa Now when I see the screenshot I sent earlier, I had very high shared memory usage. Now on a different session I have only 500MB in shared memory. Interesting...

@oldsysops @unfa But it doesn't use that much memory. 3% of my 16GB is only 480MB. Correct me if i'm wrong. Maybe I don't understand something.

@unfa @oldsysops Yeah, X.org makes sense, but why is it not known? Maybe it's hardware (driver) specific?

@unfa @oldsysops If that's a bug in the kernel, wouldn't it be a huge deal in the data centers? I wonder if that's something specific to Manjaro KDE or some application we are running.

@oldsysops @unfa That surely isn't a normal behaviour. I closed every app except terminal, disabled the swap, dropped the caches (/proc/sys/vm/drop_caches), ran the memory allocation program which was killed at 5800MB and took this screenshot. Memory usage at 10GB and no way of reclaming it. HELP

@oldsysops @unfa VM has 4GB assigned to it. Either way my PC should handle the workflow I was running then, this is: Brave browser + couple of terminal emulators (konsole) + file manager and the VM. The RAM usage shouldn't be as high as 10GB in the first place.

@oldsysops @unfa
But the problem is, it doesn't get unallocated even if it's needed!

Example (I have 16GB of ram):
I have 10GB ram used (htop) and 7.1GB is in buff/cache (free -h).
Then I run a VM in Virtualbox. The system get's very unresponsive (about 99.5% ram usage). When I kill the VM, buff/cache is still ~7GB. Can you explain that?

@unfa I have the same problem, I have browser and couple of terminal emulators opened and the RAM usage is about 11 GB out of my 16 GB's. I've used a C program to allocate memory and it went to 5 GB allocated before it was killed, after that still 10.5 GB used so it's not a disk cache problem? I'm using Manjaro KDE. (I also noticed that after I wake up my PC from sleep the ram usage grows by ~3 GB and it doesn't get freed no matter what I do) The htop also doesn't show anything suspicious.

One thing I fight with on Linux is RAM and SWAP that is being used in 10ths of GBs, yet tools like htop don't show any processes using that much memory (even when run as super user). I know that disk reads are cached, this is not the problem here though. What is eating up my RAM? Why I cannot identify processes that allocated this memory? How can I reclaim it without rebooting my system?
Help!

Wow, the Garuda Linux community really can't take any critcism...
forum.garudalinux.org/t/first-
I come to help them make their distro better and they close my topic after mocking me and refusing to discuss anything with merit.
Way to go.
Maybe I should make a video about this? :D

Just want to point out that mastodon and especially fosstodon is the most friendly social media i've ever used. It's that great

If you've been lurking on Fosstodon, intimidated by the more technical toots, feeling imposter syndrome, or just afraid to jump in, please toot an introduction, ask questions, learn, get to know others. There's nothing to be afraid of. This is a friendly and welcoming instance. Almost all of us want to get to know you except for a few grumps.😃

@textovervideo I'm pretty sure that rxvt-unicode and urxvt is the same terminal.

My Crust of Rust episode on subtyping and variance in is now up at youtu.be/iVYWDIW71jk. Even though it's a thorny topic that I'm fairly new to myself, I _think_ we managed to explain the concepts and their practical implications without too many 🍿 moments.

Hi all,

The company I work for (recently surpassed 500 full-time employees) is looking for helpdesk technicians and Sysadmins in the Montreal and Quebec City areas. If you're interested or want more information, send me a DM or an email at linuxliaison@fastmail.com.

If you know someone who's looking for a job, send them my way :)
