Hello Adam,

this happens in part of the code that (presumably) deals with
LinearScaling,
and distribution of the integration points over the nodes;
from what I see in the code, you have two options to try to get rid of
this
message:

- use more nodes, so there will be less per node (although I am not
sure if
   that actually helps here, because it may be that this part deals with
all
   points, e.g. before distribution over the nodes)
- add NOMORTON to the inputfile, so it uses a different sorting
technique

In both cases, I'm not sure if it actually works, but it may be
worthwhile
to test them out.

If it still doesn't work, please send input- and outputfile to
support_at_scm.com,
so they can try to figure out what's going on.
