Problem: The message occurs in the MPI parallel output1 file.

Impact: none


Solution: Update CLUSTERSIZE in compilation? (Source: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg04535.html) Own tests will still follow - Michael Sluydts


First version spotted: 12.1 by Michael Sluydts

Last version: 13.1 has not yet been tested, most likely still occurs.
