Hi Melvin, I have a theory here. Did the original $ROOTDIR/etc/vm.args =
file still contain a =E2=80=9C-name=E2=80=9D directive?

Multiple =E2=80=9C-args_file=E2=80=9D inclusions are OK, but when there =
are conflicting =E2=80=9C-name=E2=80=9D settings the node will default =
to nonode@nohost. When you specify both =E2=80=9C-name=E2=80=9D and =
=E2=80=9C-sname=E2=80=9D the latter will take precedence. Try removing =
the =E2=80=9C-name=E2=80=9D from $ROOTDIR/etc/vm.args and setting it =
using either of your first two methods. Cheers,

Adam

override the default search space entirely.
