3577471 - Installer/Upgrade fails with the return code is 0 on UNIX system

• When launching setup.sh while running the installer  fails with below error:
  Finished, return code is 0
• Error in strace / truss 
• "Check to see if there is enough space in the tmp dir before starting.\n# This should be performed before the setup.engine is started. \n# The min size will be 10MB or 10000.\nmintmpsize=10000\n\n# `df -k` is not POSIX compliant for all Unix variants. This means it has different outputs we need to handle in order to capture the Free/avail/Available space left.\"
  Error is "Installation aborted. The tmp directory size of $tmpsize is less than the minimum required $mintmpsize. Please free up some space for this installation."
