[CP2K-user] [CP2K:18655] error of MPI run

['yafei li' via cp2k]

Dear everyone 

I am a new rookie at cp2k. Recently, I use my computer to do some cases 
from the official website. My computer system is Ubuntu with 6 cores. 
Sometimes, I can run the calculation smoothly, but sometimes, the following 
error message will appear.


application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1
:
system msg for write_line failure : Bad file descriptor
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1
:
system msg for write_line failure : Bad file descriptor
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1
:
system msg for write_line failure : Bad file descriptor
--------------------------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, 
thus causing
the job to be terminated. The first process to do so was:
  Process name: [[30823,1],1]
  Exit code:    1

How should I solve this problem? Is it because I don't have enough CPU 
cores?
Thank you very much.

Yours
LI
