Still not solved. Linux 5.0.0-29-generic #31-Ubuntu SMP Thu Sep 12 13:05:32 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux This system has i5-9600K and 16 GB RAM, no swap.
This happens everytime I run a VirtualbBox VM. The VM has got 4 GB RAM. I updated my VMs to current default settings for Windows and reduced CPU count to 1. This solved the issue until I ran video compression on the host system concurrently. So the problem still happens when CPU usage is high and a VM is running. This time I succeeded in rescuing the system avoiding a reboot. I switched to console mode and waited a lot of time (like an hour) until I was able to kill VirtualBox. What I saw was: kswapd0 was running crazy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1518457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
