error in cluster running

Hello, I am running the protein docking task in cluster, but failed. here is my related files:

------run.sh------

#!/bin/tcsh
#PBS -l walltime=180:00:00 nodes=2
#PBS -N Rosetta_Job
# Batch-submission script for OpenPBS system

module load rosetta

cd /home/users/test

mpiexec -np 32 /opt/rosetta/rosetta_latest/bin/docking_protocol.linuxgccrelease @flags > log &

------flags------

-in
-file
-s input.pdb
# the input file should have two single, complete chains A and B
# for Ab molecules (with L+H chains) use -docking::partners flag below
-path
-database /opt/rosetta/rosetta_database
# customize this to point to your installation directory
-docking
#-randomize1
# rotates partner1 (chain A) before docking proteins together
-randomize2
# rotates partner2 (chain B) before docking proteins together
#-partners
# defines docking partners by ChainID; see manual
-out
-nstruct 3000
# this should be set to a large number for effective sampling
-mute core.util.prof
# reduces copious output, without overdoing as with -mute all
-file
-o dock_output
# scorefile will be named dock_output.sc (or .fasc for fullatom)
#-fullatom
# fullatom is commented out for fast low-res "centroid mode" run


And here is the log file

mpiexec has exited due to process rank 10 with PID 27348 on
node halo2 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpiexec (as reported here).
