did you re-install the node or remove the hb_uuid file?
those are the two usual causes.

to rectify the situation, shutdown heartbeat everywhere and remove the
/var/lib/heartbeat/hostcache file

in the future, you can either save the contents of that file or
repopulate it with crm_uuid before starting heartbeat on the new
machine (look in /var/lib/heartbeat/hostcache on the old machine to
find the expected uuid)
