I've restarted several more times.  I haven't changed any settings, but the
RWL/RBL errors seem to have gone away.  Bad cache or something?  I am
getting occasional warnings in the log that Name Server x.x.x.x does not
respond or timed out.

I can't imagine that it's suddenly the name servers.  It's all three of
them throwing this warning from time to time.  Looking at that compare (
http://assp.cvs.sourceforge.net/viewvc/assp/assp2/assp.pl?view=diff&r1=text&tr1=1.24&r2=text&tr2=1.36&diff_format=h)
it looks like some of the logic has changed / code added right around that
warning message.   Maybe the DNS servers have always been operating the
same but now ASSP is more picky?  Or could something have changed where DNS
is queried differently?  I've got DNStimeout set to 3 seconds.  I've never
seen my dns servers take that long!  I also have DNSReuseSocket checked.
