I just happened to trip over this this morning, while testing a similar
problem at one of my customers:

It appears that ucsd.edu doesn't think it is authoritative for AMPR.ORG:

harald@enfm 105> dig @128.54.16.1 ampr.org soa

The response comes back without the Authoritative Answer bit set.

Secondaries running modern version of BIND (and possibly older versions of
BIND) will not transfer a zone unless the configured server is
authoritative. Since ucsd.edu is currently not authoritative, the
secondaries are not updating.

I cannot yet answer the question "*why* would a server think it is not
authoritative for a zone"...

(Let me know if I'm way-off-base here, ok?)
