MPI problem

With help of a friend we connect my two computer and compile the model in parallel.
the problem is that when we try to run the model with one core the model run OK but when we try to use more core the run stop with a error.

the error that i get is:

kozokg@kozokg5:~/WRF/WRFV3/run$ mpirun --host kozokg5,kozokg5,kozokg5,kozokg5 -np 4 ./wrf.exe
MPI_ABORT was invoked on rank 3 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
mpirun has exited due to process rank 2 with PID 16894 on
node kozokg5 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
[kozokg5:16891] 1 more process has sent help message help-mpi-api.txt / mpi-abort
[kozokg5:16891] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages

this is the massage that i getin the rsl.error file:

taskid: 2 hostname: kozokg5

Quilting with 1 groups of 0 I/O tasks.

-------------- FATAL CALLED ---------------

I don't have any idea for resolving this problem,
Thanks in advance,

In case this helps anyone else: in my case I encountered this error because I'd accidentally swopped start_month and start_day, making start_month out of bounds.
