                          I'm trying to submit a job to a school server (HPC) with:

    #!/bin/bash
    
    #$ -S /bin/bash
    #$ -cwd
    #$ -o ./out_$JOB_ID.txt
    #$ -e ./err_$JOB_ID.txt
    #$ -notify
    
    #$ -pe orte 1
    
    date
    pwd
    
    ##################################
    RESULT_DIR=~/Results
    SCRIPT_FILE=sample_job
    ##################################
    
    . /etc/profile
    . /etc/bashrc
    
    module load packages/comsol/4.4
    module load packages/matlab/r2012b
    
    comsol server matlab "sample_job, exit" -nodesktop -mlnosplash
    
    /bin/uname -a
    
    mkdir $RESULT_DIR/$name
    cp *.csv $RESULT_DIR/$name

The job aborts saying:

    Sun Jun  8 14:20:21 EDT 2014
    COMSOL 4.4 (Build: 150) started listening on port 2036
    Use the console command 'close' to exit the program

What might be the reason and how should I fix it?
