Repeat-By:
        I've had 2 bash crashes lately while attempting to run the following
        script (Note, the 2nd crash was on loop # 14):
#!/bin/bash
declare -i counter=1
/opt/ds/src/lm1/bin/lm1_shm -c &
while [ $counter -le $1 ] ; do
   /opt/ds/src/lm1/bin/lm1_read  -s 4 -m 255 -f 4000  -a -r -g 1 -u 3&
   /opt/ds/src/lm1/bin/lm1_write -s 4 -m 15  -f 12500 -a -r -u 0 &
   usleep 10
   wait
   cat /proc/meminfo
   echo "Loop: $counter ------------------------"
   date
   let counter=$counter+1
done
