Hi,
I’ve freshly installed LEAP 15.0 on my computer. (Gnome Desktop)
After the boot, when the computer is idle, I’ve noticed there is 1.9GB used (to do almost nothing)
Quickly, when some windows are opened the computer runs out of RAM (4GB installed) and freezes.
I find it weird as LEAP 15.0 spec is only 2GB RAM.
Previously I ran LEAP 42.1 with no problems.
HAs anyone the same issue? what should be the RAM occupation?
Thanks for your help.
Have you run top to see what eats memory??
Fairly standard Gnome install here. I see the following:
some 200MB RAM in “runlevel 3” logged to a console (no Gnome…)
some 1.1 GB with one user logged to the desktop, terminal with “top” running
some 1.4 GB with Gnome System Monitor running.
To reach 1.9 GB used RAM like at this moment:
top - 17:51:59 up 7 min, 2 users, load average: 0,17, 0,18, 0,10
Tasks: 289 total, 1 running, 288 sleeping, 0 stopped, 0 zombie
%Cpu(s): 0,2 us, 0,0 sy, 0,0 ni, 99,8 id, 0,0 wa, 0,0 hi, 0,0 si, 0,0 st
KiB Mem : 16304628 total, 12954504 free, **1891200 used**, 1458924 buff/cache
KiB Swap: 16777212 total, 16777212 free, 0 used. 13903456 avail Mem
I have a terminal, Firefox with 20 tabs open, Evolution, Files, Image Viewer, LibreOffice Calc with a fairly complex spreadsheet open.
So I guess you have a RAM eater somewhere…
Hi,
Thank you all for your reply.
I haven’t succeeded to get clues from top. There are many small consumers, everything seems normal.
Here is the result of top with terminal and firefox (one tab, suse forums). Only one user logged.
Which makes 2.2GB used memory!

I wonder what application is “Web Content”? I’ve never seen it before (I never use Gnome). Is this something run in a Firefox tab? If yes, do you have it open always when you have Firefox open?
Yes, “Web Content” is something related to web pages open in Firefox (not sure if multimedia content and/or javascripts) and there may be several running at the same time. Closing and reopening Firefox might temporarily lower the amount of RAM used.
Nothing strange in what you posted, but since the (default) sort column is “%CPU”, try moving the sort column to “%MEM” with the “>” key to see if there is a hidden offender.
Ok Linux does not like non used memory to go unused so it uses that for disk cache which will be used if needed by a program but other wise is used to optimize disk access. So what “you” use is 600 meg less then the 2.2 gig shown as used. so call it 1.6 gig which is not to far from what I’d expect. the 600 meg of cache will become used if needed. and you have about 1.6 gig before you start to seriously start to use cache memory. currently you do not use any cache. Until you do I would not worry.
Sorry, that isn’t correct, it doesn’t add up:
KiB Mem : 3894244 total, 980412 free, 2295652 used, 618180 buff/cache
2295652 used + 618180 cache + 980412 free = 3894244 total
So 2.2GB were actually in use at the time of this snapshot.
I would not worry either, if the OP were not claiming that the system quickly runs out of RAM and freezes…
Are you deliberately NOT using any SWAP or is something wrong in your configuration?
Kernel memory allocation works better when (even a small amount of) SWAP is available and you would not experience a sudden freeze when you run out of physical RAM.
Here are some news.
Sorry for the delay, I have young childrens who don’t care the linux kernel…
TOP
Sorting TOP to %MEM shows me that almost 15% of memory is used by Evolution services that I don’t care actually. Seeking the forums, I haven’t found a way to stop these background services.
SWAP
No SWAP is not a choice. I didn’t change anything in the standard installation. But the partitioning since I install over the old version and start doing it with opensuse 11.2.
When running out of memory, the system slows down, you can hear HDD acces and you need many minutes to move the mouse and close windows. Generally it ends with hard shutdown, I’m not used to unstable system. Actually it is the first time since 11.2 !!
With small memory you really need swap. And 4 gig is small these days
Following your advice I’ve checked the system and noticed the SWAP partition was not mounted.
I corrected that and now the SWAP is in used and the free memory has improved.
If someone finds a way to stop the bloody EVOLUTION, that would just be perfect
Here is now the result of TOP juste after start with no application started

Upgrading the system from a previous version may lead to an unmounted SWAP if the SWAP is reformatted, changing its UUID, and /etc/fstab is not changed as well and uses UUIDs to mount partitions.
With the SWAP in use your RAM usage looks pretty normal now, you should not experience freezes anymore.
I’m using Evolution as a mail client, so I’m not willing to disable it here, but I will come back if I find something useful.
Trying to uninstall Evolution from a virtual machine install I ended up removing the following list of packages:
bijiben-lang
evolution-data-server-lang
evolution-ews-lang
evolution-lang
folks-lang
gnome-contacts-lang
gnome-maps-lang
gnome-shell-calendar
gnome-shell-search-provider-bijiben
gnome-shell-search-provider-contacts

If you can really get without all of them you can uninstall all and spare some 200MB of RAM; I doubt that this is worth the effort, but your system… your choice.
Expect a number of conflicts to be solved before the YaST-Software resolver accepts that list, maybe it is easier to start with the libe* packages.
Thank you for your advice.
With the swap activated, I no longer experience system freeze. well done.
So I think I can accept to lose 200MB RAM, I will probably have more pb by removing all the evolution related packages.
all the more as today I have an other pb : after lost of power supply when resuming from suspend, I no longer have internet connectivity…I’m going to start a new thread :’(
