No idea. Nanny is RedHat's monitoring widget, and is supported by them
as part of the Piranha package.

Well... if nanny cannout connect to the HTTP server on your realservers,
it won't work.

That said I notice that the virtual service is on the webcache port...
are the realservers webcache servers or HTTP servers? If you change
from :80 to :3128, does the behaviour change?

My next suggestion would be to try ldirectord and heartbeat together, or
keepalived on its own - they're better understood here.
