Public bug reported:
I'm running the 20160115 daily xubuntu build, xenial-desktop-amd64, live
from a usb drive. The Xfce4-power-manager package (version
1.4.4-4ubuntu2) seems to have a memory leak, consuming all 4GB of RAM
when running for more than an hour on a Core i3 notebook (Acer E5-471
with a Sanyo AL14A32 battery). Xfce Power Manager settings are at
default.
I boot with AC power connected, and the task memory starts growing
immediately. It stops increasing and remains constant, when I unplug AC
power. When I boot and run from battery, the problem does not appear:
the task uses about 17MB and is steady.
I've never seen anything like this in previous xubuntu releases.
Task Manager reports the task as
"/usr/lib/x86_64-linux-gnu/xfce4/panel/wrapper-1.0
/usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libxfce4powermanager.so 5 8388654
power-manager-plugin Power Manager Plugin Display the battery levels of your
devices..."
