It used to be that this situation caused a counter increment and was
otherwise silent.

This is the first time I've seen a report of the situation you describe.

Is there anything interesting in the syslog on the sending system?

What does 'ntpq -p' show on both machines?

There are some patches around peer mode in 4.2.8p7, scheduled for public
release on Tuesday the 26th of April.  I have no idea if they will fix
the situation you are seeing or not.  The peer mode tests have been
working fine for me and several others who have been testing it.
