deadtime - set failure (death) detection time
The deadtime directive is used to specify how quickly Heartbeat should decide that a node in a cluster is dead. Setting this value too low will cause the system to falsely declare itself dead. Setting it too high will delay takeover after the failure of a node in the cluster. Please read the FAQ document for more information on how to configure (tune) this important parameter.
The deadtime value is specified according to the HeartbeatTimeSyntax. Two sample deadtime specifications are shown below.
deadtime 10 # 10 seconds deadtime 250ms # 250 milliseconds (1/4 second)
