Could it be that you are running openmpi and it by default wouldn't allow you to engage more tasks than your physically installed cores (i.e., 4)? The failure of other parallel tests exceeding 4 tasks would confirm this. You can limit the maximum task-count with the variable MPI_TEST_MAXPROC in your cmake command. Easy check if limit applies is to do a mpirun -np 8 echo "hello world" in the shell
