I cannot answer your question, but I suspect it might be useful if you mentioned which version of heartbeat and what resource manager you are using. Perhaps provide a copy of your heartbeat configuration. Is heartbeat using too much CPU? It should be pretty much idle relative to the rest of the system - If not, it is worth finding out why not.
