Thank you very mutch for these explanations.

Unfortunately, I'm quite sure that the two setup() calls are from the same 
instance and in the same request. We can see that very clearly in the logs. I 
included an excerpt from the logs in my reply to the mail from Joerg Heinicke 
in this matter. You will find further explanations there, too. If you are 
interested in my problem further on, please look there.

Best regards,
