Sure, but my point was it's not a leak. Being memory inefficient is one thing. Leaking memory is where, over time, it takes more and more memory because it is not properly freeing up memory it has finished with. You need to sample the memory usage more than once to establish that some is being lost to leaks. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

OT: just falling back to fluxbox after Gnome3 mem-leak experince

Has gnome-shell been running for 16 days? It is supposed to show that I do not regularly shutdown the laptop and use the suspend/hibernate function. Not gnome-shell only of course but Linux kernel and some other applications too. ;-) -- Peter -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

I am not sure, but I suspect you misinterpret those numbers. This is the
amount of memory that the application thinks is available for itself.
This does not equal the actual memory requirements of the process.
My system currently shows:
$ ps aux | awk '{ print $5 }' | tail -n +2 | awk 'BEGIN {s=0} {s+=$1} END
{print s}'

-/+ buffers/cache: 9092483046020

The sum of all processes' virtual memory sizes is about nine times the
size of actual memory in use (887 MiB vs. 7.8 GiB with only 4GB of
physical RAM available, no swap).

You are probably right with not best lines shown from status file.
Anyway I saw that gnome-shell consumed more than 1100MB(=approx. 29% of
4GB real mem) for VmRSS. System was swapping and the only application
consuming more than 10% of memory was ?guess? ;-)
