fyi, the below is from /usr/src/UPDATING:

COMMON ITEMS:

        General Notes
        -------------
        Avoid using make -j when upgrading.  From time to time in the
        past there have been problems using -j with buildworld and/or
        installworld.  This is especially true when upgrading between
        "distant" versions (eg one that cross a major release boundary
        or several minor releases, or when several months have passed
        on the -current branch).
