That's enemy action.  There is a remote crash bug in older versions of
named.  You need to upgrade to at least version 8.2.3-REL, or
preferably 8.2.4-REL (which is what's in 4.4-STABLE) or 9.1.3 which is
in ports.

These are all innocuous.  You can get rid of the line about "Default TTL"
by adding the line eg.

$TTL 86400

to you zone file.  That will set a default TTL of 1 day, which is a
reasonable enough value if your zone files don't change very often.
