This Integer32 (256..2147483647 kilobytes) is described as the soft rekey interval lifetime in kilobytes for this IKE policy entry, again flagged deprecated since it derives from the hard-kilobytes lifetime rather than being negotiated. An admin managing volume-based rekey behavior should look at the hard-kilobytes object instead of tuning this one directly. For example, an admin noticing unexpectedly early volume-triggered rekeys would check csOrionIKEPolicySaLifetimeHardKbytes as the real control, not this soft value.
