Dear Graeme,
             I configure redhat piranha fos on two systems for web
services. When I configure NTP server to another machine and make ntp
client these (piranha fos web server) servers. But as soon as ntp
service start these client servers disturb piranha fos and piranha
create VIP address on both servers.
