Have had two or three more instances of this oom-killer behavior. Today we also had an incident where the system really DID run out of memory, but oom-killer did not kick in. I noticed the box being sluggish and disk churning, so I started system monitor and watched it happen. One of the firefox web containers was using up 11+ GB of memory. There was no available core memory, no available swap, and pretty soon desktop froze. Was unable to switch to a non-desktop pty or do anything, disk churning away relentlessly. Waited a little while, and then used the reset button on the box to reboot.
After that happened, we've installed upstream kernel and are running it right now. $> cat /proc/version Linux version 5.0.0-050000rc1-generic (kernel@tangerine) (gcc version 8.2.0 (Ubuntu 8.2.0-12ubuntu1)) #201901062130 SMP Mon Jan 7 02:32:47 UTC 2019 So far, unable to induce an oom-killer anomaly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1811093 Title: Bogus "Out of Memory" compiz invoked oom-killer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811093/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
