I use heartbeat & ldirectord here, ~2 years with no issues. Horms (project
owner) responds very quickly to issues. Source code for "checking"
mechanism is perl, so if perl's your thing it's handy to have and easy to
modify...

I use keepalived for its VRRP/HA qualities on my linux routers. Alexander
(project owner) is pretty responsive too. I like this setup a little more
than ultramonkey because of my experiences with routers in the past. But I
don't see this as a reason to switch from my perfectly working linux-ha
setup with Ultramonkey..

I'd use the other two before this one. Almost nobody uses the mon-based
solutions anymore. Not because they don't work, it's just that much more
active development is happening in the other two.
Hope that helps
