Memory swap full

[uerlii]

okay, my pc is Celeron 3865U with 4G ram and 512gb HDD, I put 2gb as swap in my pc but usually my swap memory fill up, I dont know how i resolve it

I try change swappiness for 10, but nothing happened. someone else know resolve?

Welcome to the forums,
this is a hotly debated question, how much swap file capacity do I need, the answers ranges from none at all to 1tb
So, you can have several swap partitions, on my old dell laptop with 4gb ram and LMDE5/Parrot, I do not have a swap file, and it runs just fine, my desktop has 8gb ram, and the system monitor has never got above 30% [it is used for general computing, streaming, etc [not gaming]] and also has no swap file
I suggest you read this article,it will tell you how to add extra swap files and you can see the results of a survey they carried out prior to publication.

What's the right amount of swap space for a modern Linux system?

Hello @uerlii,
Welcome to the Linux.org Forum.
Which file system are you using? as a rule of thumb swap should be at least as big as your ram and some say twice as big so your should be at least 4 GBs. How ever with 4 GBs of ram you should not be seeing much Swaping going one unless your doing video editing or some other very heavy tasks. So if swap is being filled I would say there is something amiss on the system ram. Do a check of your ram first make sure it all working.
Good Luck.

It's going to depend in part on your computer usage. If you open heaps of documents and reams of web pages and run lots of programs, some in the background, your 2G swap could easily be used up. If you use your computer discreetly, you'd likely get a different result. If, for example, you are using the computer modestly, say just a browser looking at a few static web pages successively, and swap still fills up, then that would indicate a problem, but it would be very unusual because the linux kernel has very efficient algorithms for it's swap usage.

The first step you might consider is to upgrade your software to the latest versions, including the kernel if you haven't done so already.

Modify /etc/sysctl.conf with these 2 lines, then reboot.

vm.swappiness = 5
vm.vfs_cache_pressure=50

I think it'd be good to know more information.

Describe your computer usage to us. Do you have a lot of applications open? Do you have a lot of tabs open in your browser? If so, which browser are you using?

That sort of stuff. There's not necessarily a 'magic fix' for this.

Yes there's a magic fix...add more Ram...problem solved.

This CPU can handle 32GB of Ram. https://laptopsreviewer.com/product/intel-celeron-3865u/

 

[uerlii]

Thank you for all the people answer my doubt.
I decided, I will add more ram like @bob466 say

@KGIII I saw, I use edge browse for study so I edit PDF on it.

@Brickwizard
I decided also desactive swap while I dont have enought memory

and how I close this thread?

 

[Lord Boltar]

How many kernels do you have on your machine? run

find /boot/vmli*

this will tell you - if have have a bunch uninstall all but the last two kernels - this will free up space in swap

and how I close this thread?

We leave them open here, in case you need to come back with more, or if another Member has additional help for you.

Cheers

@Lord Boltar only 1 "/boot/vmlinuz-linux"

To clear the swap memory on your system, you simply need to cycle off the swap. This moves all data from swap memory back into RAM.
Here are all of the commands you'll need!

Check space:

free -m

Disable swap:

swapoff -a

Wait approx 30 sec
(use free -m again to see the amount of swap used/available decrease over time)

Enable swap:

swapon -a

I had you check for multiple kernels earlier because if you clean the swap file it will reload with all the extra kernel swap into the one swap, but since you only have the one that is good

You can try disabling hardware acceleration. The symptoms you describe are quite similar to what's seen when Chromium-based browsers have HA enabled and causing trouble.
