There may be a limit but it is much higher than 4. That is a pretty
old version of heartbeat, I don't recall all the changes that
have been made but the IPAddr management script has been
updated several time. Try 1.0.4 which is the latest (and greatest)
stable release. 

It can be found at http://www.ultramonkey.org/download/heartbeat/ 
(the linux-ha.org web site is still wating for an update).
