DL_POLY_2 limits the number of valence angle potentials in the system
to be simulated (actually, the number to be processed by each node)
and checks for the violation of this. Termination will result if the
condition is violated. Do not confuse
this error with that described by message 50 (above).
Action:
Standard user response. Fix the parameter mxangl. Consider the possibility that the wrong CONFIG file is being
used (e.g similar system, but larger size.)
