[Mimedefang] Recent Razor issues

[Lee S. Whatley]

I've been getting several of these lines in logfiles since yesterday:

mimedefang-multiplexor: Slave 42 stderr: razor2 check skipped: No route 
to host IO::Socket::INET: connect: No route to host^I...propagated at 
/usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/Dns.pm line 393.

I doesn't seem to happen with every message, just every couple of 
minutes.  Has anyone else experienced this problem?  What should I do?  
It almost seems as if either my network connection is getting crappy or 
razor's network connection is getting crappy.
