Thanks Greg
One correction. The new server is FreeBSD 9.2, not 9.3. Replies below

Yes, that makes sense, but I'm using the same client in both cases. In
rc.conf on client, I have:
nfs_reserved_port_only="YES"
nfs_client_enable="YES"
amd_enable="YES"
And ps shows the amd process started with these flags:
/usr/sbin/amd -p -a /.amd_mnt -l syslog /host /etc/amd.map /net /etc/amd.map
amd.map is the default
$ cat /etc/amd.map
# $FreeBSD: src/etc/amd.map,v 1.10.8.1 2009/04/15 03:14:26 kensmith Exp
# $
#
/defaults type:=host;fs:=${autodir}/${rhost}/host;rhost:=${key}
* opts:=rw,grpid,resvport,vers=3,proto=tcp,nosuid,nodev
This is the same default amd.map as 9.2.
Another data point: I see the same behavior with a 9.2 client: I can
automount a share from my 6.3 server, but not from the 9.2 server.
Thanks
