Hi Hanh, These are logical interfaces. Why would they require considerably more memory in LDoms than on bare metal? I just verified that creating 254 logical interface in an exclusive IP Instance non-global zone is not a problem, and the system (V210) has 8GB (don't know how much memory this took up). On an x86 system, doing a similar operation reduced memory by 200KB, and that may have been the script as much as the logical interfaces.
