Issue:
When executing a File Transfer or JOBS with an Host Group the user gets the folowing error: 
 
U00011000 'JOBF.???.???.???' (RunID: '0012345678') could not be started on 'XYZ123/'. See next message. 
U00011021 Host ' ' is not active!

The task also produces Forced Traces. 
The error only occurs when you set the Host Group's Mode to 'All active' or 'All active and inactive'. 
Resolution:
Workaround: use Mode 'First' on the HOSTG instead of 'All active' or 'All active and inactive'.
