Arch Linux

Description:
When xloadimage is used to set the root window background it leaves "junk X clients" open
causing the server to become full after some runs and no longer let other windows open (DoS situation on X).
Very easy to hit the cap after some time with applications that set the bg many times, like xscreensavers or conky.


Additional info:
* xloadimage version: 4.1-9 from community repo
* xorg-xserver version: 1.9.4-1
* arch: x86_64
* attached output of "xrestop -b -m 1"

I think this is the same issue or related to the one reported in Debian here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=325689
and they seem to have fixed it.


Steps to reproduce:
1. Count X clients with xrestop:
$ echo $((`xrestop -b -m 1 | wc -l` / 16))

2. Set root bg with xloadimage or xsetbg:
$ xloadimage -onroot /path/to/image.jpg

3. Repeat steps 1 and 2 a couple of times and watch X clients increasing with each run.

4. Repeat enough times and the X clients list gets full (255) leading to the following error when new X apps try to start:
"Maximum number of clients reachedMaximum number of clients reachedError: cannot open display: :0"
