  You should use the new syntax to define home servers.

  Also, you may want to grab a recent copy of the source from
http://git.freeradius.org/pre/.  It fixes a bug where it would send
Status-Server messages, even if "status_check = none".

  Or, you can use the new syntax for home_servers to set "check_interval
= 120", which should cut down on the traffic a lot.

  And if you want a stable RADIUS system, you *should* enable
status-server checks.  It lets the proxy use the partners server as soon
as it's up, rather than trying it while it's still down.
