Most recently the problem happened at 22:29:16.419070807. Looking in
all of my logs (not just syslog), the only thing that happened near that
time was that a host on my LAN sent a DHCPREQUEST at 22:29:07 (which the
DHCP server answered with a DHCPACK) and then at 22:29:58 Shorewall
dropped an attempt to connect to port 2433 from a host on the Internet.
I have already changed resolv.conf back to my preferred configuration
and I will check again for correlated log entries when it is changed
