df command in script is returning with incorrect error code

Issue

• An issue exists in which the dfcommand in a ksh environment is returning high value return codes that are causing our application not to be allowed to be installed.

• Tracing a ksh script that is using df displays the following:

   + df -kP /opt/IBM/ITM
   + 1> /dev/null 2>& 1
   + [ 38720 -eq 0 ]

• The last line indicates that df is returning with an error code of 38720
