There is a bug in Cray's PMI-3 which causes this error message. Change the platform file to point at PMI 2.1.4. I was hoping Cray would fix the bug before 1.7.0. Since that doesn't appear to be the case I will push updated platform files that use PMI 2.1.4 instead of the default.

Never seen this error before. What PE release is installed?
