    generating, by a slave daemon, a list of care relationships, each care relationship involving a process that originated at the failed node;

    sending by the slave daemon, the list of care relationships to the surrogate origin node;

    receiving by the surrogate origin node, the list of care relationships; and

    reconstructing, by the surrogate origin node, a complete set of care relationships for processes that originated at the failed node.
