This read-create value, in seconds and defaulting to 10, sets how long the node waits without receiving an ICR keepalive from its peer before declaring peer loss. Admins tune this alongside rbnIcrKeepAliveInterval to control how quickly a failover is triggered when the redundant peer becomes unreachable. Setting it to 30 would give the peer 30 seconds of silence before this node declares it lost and potentially takes over as active.
