CLUSTER function problems [message #42651]

I have a question regarding what to expect from the clustering
function.
I am trying to split my dataset up into 2 different groups but
sometimes the CLUSTER function refuses to split the data in groups.
I call cluster weights with n_clusters=2 and it returns two rows of
cluster centroids as well.
The CLUSTER function (also called with n_clusters=2) then assigns all
observations to just one of the groups.
I assume this has something to do with the criteria of inter/intra
group variability?
When n_elements is specifically set to 2 then shouldn't that be the
endpoint criteria and other criteria laxed to comply?

Best regards
Soren
