Fedora 40 using sometimes 90% RAM when browsing/vscode

I often find the system locking up and having to do a force shutdown, any tips for how to combat this?

Please share details of your system as preformatted text, the </>, of the output of inxi -Fzxx.

Memory seems kinda low now 11GB lol but I’ve only got the browser open

can you share a screenshot of the system monitor tor see if it’s vscode that’s using that amount of ram?

Seems to be better now! I dunno lol too many tabs maybe…

I fixed the formatting of the inxi output for you,

You have lots of memory. If you see problems again we will need to check the journal logs to find out what happened.

FYI it is normal for a linux system to use all the memory of the system to optimise performance. For example caching file system data in memory.
Once an app needs memory linux will cache less to allow the app to run.


Thanks legend

Added memory
