In upgrading to the latest version of bind available as of Nov 29, 1999, the following error is generated in /var/log/messages on records that were ok before: Nov 29 07:30:00 roy named[20125]: Zone "foobar.com" (file other/foobar.com): No default TTL set using SOA minimum instead
This is an error in your zone file, not a bug in bind. In the parentheses after SOA, you can now specify 6 values. Check the documentation for details.
