Since the upgrade everything is fine no more core dumped. The only point is I lost 2 zfs dataset after the reboot, of course it's the both dataset give me the core dumped. It's not a big deal for me because it's only backup. The point is before I upgrade I check the partition with find/md5, zfs scrub etc... and everything seem fine. Anyway thanks.
