A similar bug happened here on 2 different Ubuntu installs once they upgraded to Ubuntu 18.10.
Another symptom of the bug was periodic addition of IPv6 addresses to the `ip addr` listing. If you wait a while, the list had thousands of IPv6 entries in it! Apparently every time it decided to fetch new IPv6 addresses it also did a RST on all the IPv4 connections, which is why webpages fail to load a lot of the time. Once I completely disabled IPv6 support on my machine via: /etc/sysctl.d/99-sysctl.conf:net.ipv6.conf.all.disable_ipv6 = 1 /etc/sysctl.d/99-sysctl.conf:net.ipv6.conf.default.disable_ipv6 = 1 /etc/sysctl.d/99-sysctl.conf:net.ipv6.conf.lo.disable_ipv6 = 1 The problem went away. So I don't know what the exact problem is -- but this narrows it down. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799265 Title: avahi-daemon high cpu, unusable networking To manage notifications about this bug go to: https://bugs.launchpad.net/avahi/+bug/1799265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
