Sorry, that did not help. There seem to be a new error in the messages 
file every time I attempt a named restart though. See below for the latest:

Sep 19 23:01:27 ipa01 named[12638]: default realm from krb5.conf 
(IX.TEST.COM) does not match tkey-gssapi-credential (DNS/ipa01.ix.test.com)
Sep 19 23:01:27 ipa01 named[12638]: configuring TKEY: failure
Sep 19 23:01:27 ipa01 named[12638]: loading configuration: failure
Sep 19 23:01:27 ipa01 named[12638]: exiting (due to fatal error)
