The setup is one single server, no state sharing, in fact nothing out of
the ordinary with regards to the IdP.

The host system is a FreeBSD 9 jail, and I simply copied the jail to
another machine and changed its IP address.

After stopping the initial jail, I changed the IdP A record to point to the
new IP, I started the second jail with the new  IP and started seeing these
messages for a couple of minutes. I reverted back to the original jail as I
hadn't expected to run into this kind of trouble.

Kind regards,
