[Once again for the list. Sorry Amos.]

For further reference this was caused by resolvconf on debian which
triggered a 'squid -k reconfigure' every hour or so (hourly reconnection
of a VPN).

During the time of the reconfigure (10 secs or so) squid displayed the
above message which, I have to say, is way too misleading.
