Actually, the frequency this is logging is really quite odd too.

I rebooted my system at about 14:43, and then ssh'ed into it from another system at 16:22. As noted earlier /var/lib/ubuntu-release-upgrader/release-upgrade-available is used to determine if a new release is available, that file is created by /usr/lib/ubuntu-release-upgrader/release-upgrade-motd which is called by /etc/update-motd.d/91-release-upgrade so it seems like something is wrong with release-upgrade-motd or how often it is called.
