It seems that there is a problem in your submission script,
more precisely in the mpirun/mpiexec options.
Your MPI hostfile could be of the kind

node0
node1
node0
node1

NWChem is not going to work with this kind of settings, the hostfile should be of the following form, instead

node0
node0
node1
node1
