I am trying to run 4D_VAR WRFDA on Cheyenne, but every time I submit the job for the model; it only runs for the first two model days (of 3.5 days) and then it stops. I get no error from the rsl.error files, but when I look at my da_wrfvar.o9382425; the following error shows up:

MPT ERROR: MPI_COMM_WORLD rank 187 has terminated without calling MPI_Finalize()
aborting job
MPT: Received signal 11

Any assistance would be great!
