Details

Description:
After a few days of uptime, I noticed that xorg-server allocated around 1.3Gb memory.

Additional info:
* Intel HD Graphics 3000
* xorg-server 1.18.4-1
* 4.7.1-1-ARCH #1 SMP PREEMPT Wed Aug 17 08:13:35 CEST 2016 x86_64 GNU/Linux

xorg-server dependencies:
* local/libepoxy 1.3.1-1
* local/libxdmcp 1.1.2-1
* local/libxfont 1.5.1-1
* local/libpciaccess 0.13.4-1
* local/libdrm 2.4.70-1
* local/pixman 0.34.0-1
* local/libgcrypt 1.7.3-1
* local/libgpg-error 1.24-1
* local/libxau 1.0.8-2
* local/xorg-server-common 1.18.4-1
* local/libxshmfence 1.2-1
* local/libglade 2.6.4-5
* local/mesa-libgl 12.0.1-7
* local/xf86-input-evdev 2.10.3-1

Steps to reproduce:
* Boot a system, work as usual. Xorg memory consumption will slowly raise.

Xorg.0.log.old (33.6 KiB)

10 days uptime and normal xorg memory consumption (through kde system activity): 61 536k
* with mesa/llvm/amdgpu from git so probably not a xorg problem/leak

There also two pmap results (with about one minute difference between the checks).
Need to notice that the same version of xorg seems to work nice inside a virtualbox.

Is there any additional actions to narrow the issue?

xorg-pmap.1 (17 KiB)

xorg-pmap.2 (17 KiB)

xorg-pmap.diff (0.5 KiB)

Can you try with xf86-video-intel instead of the modesetting driver?

Comment by cyberxndr (cyberxndr) - Tuesday, 30 August 2016, 09:29 GMT

There is no leaks with xf86-video-intel. All seems to work fine.

What is the better place to report this issue (xorg + modesetting)?

product: Xorg

Is it still an issue with xorg-server-1.19.x?
