Description: Ubuntu 16.04.1 LTS
Release: 16.04
2) ouroumov@Box:~/Desktop$ apt-cache policy mate-panel

Installed: 1.12.2-1

3) mate-panel memory usage should stay about constant
4) mate-panel memory usage increases over time
-------------------
Steps to reproduce:
On a dual screen system running Ubuntu MATE 16.04.1 LTS:
- Start Eye Of MATE (eom) image viewer in fullscreen slideshow mode on a folder
with enough pictures that they won't all fit in cache.
If no such folder is available, one can create one using the
following commands (will take a while depending on your bandwidth and
processing power):
sudo pip install youtube-dl
youtube-dl -f 266 https://www.youtube.com/watch?v=6tmbeLTHC_0
mkdir frames
mplayer -ss 45 -vo jpeg:outdir=$PWD/frames/ NASA\ _\ Thermonuclear\
Art\ –\ The\ Sun\ In\ Ultra-HD\ \(4K\)-6tmbeLTHC_0.mp4
This should result in a folder ./frames/ with about 40GB of HD pictures.
- Monitor Memory usage of mate-panel using the command:
top -b -d10 -p pid | grep -E --line-buffered " pid " | tee -a
out.log
(where pid is the pid of mate-panel)
- Let it run for a few hours then use the log file to graph the resulting memory
usage data, you should obtain something resembling the graph at the end of this
thread:
https://ubuntu-mate.community/t/possible-memory-leak-in-mate-panel/7717/15
Note: I was also monitoring eom on that graph, to correlate with mate-
panel's cpu usage so the graph you obtain won't have so many lines.
