If the required simulation has constraint bonds DL_POLY_2 attempts
to apportion the molecules to processors so that, if possible, there
are no shared atoms between processors. If this is not possible, one
or more molecules may be split between processors. This message
indicates that the code has failed to carry out either of these
successfully.
Action:
The error may arise from a compiler error. Try recompiling INTLIST
without the optimization flag turned on. If the problem persists it
should be reported to
the authors, (after checking the input data for inconsistencies).
