Using a lower value for cluster heartbeat interval reduces the failure detection time but increases the risk of a false failure because of a transient problem (such as an overloaded CPU). Tuning cluster heartbeat interval to a larger value reduces the risk of a false failure but increases the time needed to detect a failure.
