.tmp file errors

[Kolaczynski, Robert]

One of our accounts keeps returning empty tmp files.
Not sure if it references to and "xfr" bug in BIND.
I've included the fact that the db.atomictangerine.co.uk has many hosts
appended for resolution.
Included also is the /var/named/boot-files/named.co.uk extract to show where
the
site registered is referring to slave status rather than master.
Any help would be appreciated on how to remove stop these .tmp files.
