To fix this, the trimming mechanism has to be disabled:

  1. Open the imss.ini file in the "/opt/trend/imss/config" folder using a text editor.
  2. Add the following setting under the [general] section and set its value to "no".

    [general] EnableTrimSpaceExpression=no

     
    The default value of this key is "yes" which enables the mechanism.
  3. Save the changes and close the file.
  4. Restart scanner service using the following command:

    /opt/trend/imss/script/S99IMSS restart
