Ok.

Ok.  Looks good.  I forgot to ask, can you post your keepalived.conf file?

This is a common problem.  You are using both vrrp and healthchecker, right?
Here are some interesting threads for you to read:

Without a configuration I can't be sure, but you can try modifying your init
script to run two separate daemons:
  keepalived --vrrp
  keepalived --check

Well it sure looks like it got confused ;-).
