This was discovered in the course of investigating the cause of ESCOMP/CTSM#2478:

 8587 dec0646.hsn.de.hpc.ucar.edu 162: forrtl: severe (408): fort: (2): Subscript #1 of the array RIO_TERMNINDIV_CANO_SISCPF has value 469 which is greater than the upper bound of 468

This came in with 464af4c, but wasn't uncovered until now when the derecho pe layout configuration for 4x5 grids was update to run across more than one node.
