Why all the HBA "ff" Even then, do I get the OFFER from the secondary?

The most likely cause of this behavior is
that the primary is not answering quickly
enough.  The "load balance max seconds"
tells the two servers to reply even if they
aren't the selected server if the client
has been waiting more than the indicated
time.

You should check to see if your client
is setting the secs field - either incorrectly
or because it is resending and it has been
some time since it started.
