Arif,
It's probably better for you to wait for a reply from SAP.
The difficulty is that we have turned a thread into a one-on-one Q&A session.
If it was my system and I was in front of the keyboard, there is so much more analysis I would do given that I could read the logs fully and branch off and test other things.
SAP will have the above luxury as you will have opened a connection for them.
Good luck moving forward. Tasty little issue to get your teeth into.
Cheers,
Amerjit
