1.4 supports IXFR. Can you look on the queries that go in and out? Does
BIND ask for AXFR?

If there is more than one update of the zone in OpenDNSSEC, the tmp
directory should hould a <zone>.ixfr file.

You can also test IXFR responses by sending zone transfer requests with
dig/drill to OpenDNSSEC, although both tools are quite buggy when it
comes to IXFR/TCP.

Best regards,
