FYI, I decided to do this: $ sudo swapoff -a && sudo swapon -a $ free -h total used free shared buff/cache available Mem: 15Gi 5.9Gi 4.8Gi 2.0Gi 4.8Gi 7.2Gi Swap: 15Gi 348Mi 15Gi
Even though I am no where near needing to swap, after the swapoff/swapon, it immediately climbed back up to 348M. Oddly, I did it again after flushing the page cache, and the swap stayed at zero: $ sudo sync ; sudo sh -c 'echo 1 > /proc/sys/vm/drop_caches' $ sudo swapoff -a && sudo swapon -a $ free -h total used free shared buff/cache available Mem: 15Gi 5.6Gi 6.8Gi 2.6Gi 3.1Gi 7.0Gi Swap: 15Gi 0B 15Gi I don't know if flushing the page cache is related or coincidence with the second swap clearance. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
