 Posted: Wed May 13, 2015 1:05 am Post subject: X Window consumes all memory |
 |
|
Recently I started getting an odd problem. The computer would hang or reboot after a few weeks of uptime. The last 2 times I noticed that shortly before it /usr/bin/X would eat all available memory, which is 12-15 gigabytes.
Once I managed to start htop when the system got sluggish, but hasn't frozen yet, and saw who got all memory; the other time /var/log/kernel/current had a line: | Code: | | [kernel] Out of memory: Kill process 13179 (X) score 639 or sacrifice child |
What could be causing this? How do I stop it?
x11-base/xorg-server-1.17.1-r1 and before that 1.16.4
x11-base/xorg-drivers-1.17 and before that 1.16
x11-drivers/ati-drivers-15.1 and before that either 14.4_p1 or 14.12-r3
kernel 3.12.13 AMD64
KDE 4.14.3
emerge --info: http://pastebin.com/QurDT4C8
The only programs running at the moment when it happened were Firefox, Skype, Konsole, MC, and often qbittorrent. I use xrandr to rotate the image by 90 degrees when X Window starts. I have launched mplayer many times, but it wasn't necessarily working when the system crashed. |

I understand your desire to blame everything on Microsoft, but the time I started htop Skype occupied only 20-something megabytes, and it wasn't Skype that got OOM-killed.
Or can there be a situation when a bug in Skype causes memory leak in X? |

Looking over my post I don't recall mentioning Microsoft.
If fact post Microsoft buying Skype and releasing an update I had not experienced the same memory leak that ground my system to a halt a number of times

Then it's not Skype. I'm using net-im/skype-4.3.0.37-r5
On another forum another user has had a similar trouble with X. When CPU load was high, X would start grabbing memory and actively using disk until it got OOM-killed. His troubles stopped after he reconfigured the kernel. Do you have any suggestions what to change in the kernel configuration? |

why can't it be that? there was nothing in recent patchnotes to say a memory leak was fixed. I was just informing you that I had issue with skype and memory leaks prior to MS purchase refuting your claim it was because it was microsoft

If skype eats 16G of RAM, what would be auto-killed? skype or X?

How does htop determine memory associated with X? does it include plasma-desktop, if plasma-desktop has its separate lines? |

Could you install and run xrestop and look (and post  ) the top consumers? |

It took me over a week until I felt the symptoms again.

When I ran another Firefox profile, with more open tabs, it consumed around 150 000 K in "Pxm mem". I had to stop it, because the system was starting to get sluggish. The one with only 6 tabs takes only 15 141K.

Opening more than 2 GPicView windows simultaneously also causes memory leaks in X. This one-liner eats about 770K per cycle (385K per window?):
| Code: |
for f in {1..10000}; do echo $f; gpicview image1.jpg & gpicview image2.jpg & gpicview image3.jpg & gpicview image4.jpg & sleep 1; killall gpicview; done
|
I wonder if it's a coincidence that xrestop gives Pxm mem = 393K per gpicview instance. |

| Memory leaks stopped (or got very small) after I replaced closed driver with the free one. |
