Any suggestions?
ARMCI-MPI (wiki.mpich.org/armci-mpi/index.php/NWChem) eliminates all ARMCI-related segfaults on InfiniBand. If it doesn't run with ARMCI-MPI, you need more nodes, which is to say, you've exceeded the actual limit of memory. On the other hand, ARMCI-OPENIB segfaults for any number of reasons, many of which are not actually running out of memory.
