I believe your question is my question 2 above, to which I don't have an answer. They're not entirely arbitrary, more or less built to try and have a continuum of values. Basically trusted services (unity, etc.) are zero. Then we put the focused application below that at 100. The dash is 200 so if there is no focused application it is the lowest. Then unfocused applications are 900. Hand-wavingly that means that a focused application would be allowed to use 8 times as much memory as an unfocused application if memory size was the only thing taken into account. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478853 Title: OOM scoring kills the browser's render process while the browser is running To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1478853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1478853] Re: OOM scoring kills the browser's render process while the browser is running
@greyback, it seems that upstart-app-launch just sets the score for paused apps at 900, and changes them back to 100 after being resumed. I wonder where these numbers came from, and how OOM Killer further prioritizes processes with the same score. 900 seems pretty high, but I really don't have much experience with this so I'm not sure. As a hack, would reducing the score of Oxide (or whatever is actually affected by this) by 30, or so, points have an impact? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478853 Title: OOM scoring kills the browser's render process while the browser is running To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1478853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1478853] Re: OOM scoring kills the browser's render process while the browser is running
There's not enough information here to make a proper attack on this issue, and this is a complex topic. We need someone to sit down and determine things like: 1. why did the OOM killer strike a foreground app? Did it use an insane amount of memory? If a webapp, is it a QtWebkit-based app, or Oxide? Does Oxide cache much in memory? 2. would more graded OOM scoring really make an impact. How much does the OOM killer take this score into account. Maybe the scores being currently set are not strong enough. 3. Is the OOM killer cgroup aware? Can we be sure it won't kill any process in a cgroup that is containing the app currently focused by the user 4. is the default kernel OOM killer really the right thing to rely on for a phone? I believe it tries to prioritize killing memory-greedy apps over longer-running ones, i.e. if your app starts eating lots of memory, it'll kill it first. I don't think Android uses it 5. has anyone profiled these apps to see if easy memory savings could be made? Are they loading large high-res graphics? 6. has anyone profiled unity8/maliit/dash and all the system services to try reduce their memory usage? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478853 Title: OOM scoring kills the browser's render process while the browser is running To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1478853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

When in the background, the renderer process should be stopped together with its parent. However it will continue using memory.
