In my case ( see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460985 ) the culprit generating huge I/O throughput was in /etc/cron.daily/man-db
It's such a long-standing and persistent bug that the default advice I give nowadays to people complaining about their ubuntu "got stuck again" is to run "sudo killall -9 find". That's really a shame: - it's not some random IO spike coming from nowhere - it's not 3rd-party, it's in default install - it's reproducible Yet, we still don't even have workaround, let alone proper policing IO of all the background tasks shipped in default ubuntu install. Hopefully migration to systemd timer units would help tackling it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/131094 Title: Heavy Disk I/O harms desktop responsiveness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/131094/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
