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.
