hello,

i'm running a raman task and it looks like it finished but i get this error in the end:

vib:animation  F
------------------------------------------------------------------------
task_raman: nfreq failed 0
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
53: task dft raman
------------------------------------------------------------------------
------------------------------------------------------------------------
An error occured in the Runtime Database
------------------------------------------------------------------------
For more information see the NWChem manual at http://nwchemgit.github.io/index.php/NWChem_Documentation


For further details see manual section:
0:task_raman: nfreq failed:Received an Error in Communication
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 DUP FROM 0
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.

any idea what happened?
