Well a number of strange things may be happening with your model
specification and your data... Check that you don't have
underidentified model (in other words, that you are not estimating the
same constant or same slope twice); and check that you have the most
recent version of -gllamm- and all the required programs (see
gllamm.org). Without any further information, nobody on this list will
be able to help you -- Nick Cox FAQ makes all sorts of suggestions as
to what should be included in your posting.
