Find out the solution for it after months... With latest release 12.2.1.2.0, this issue does not occur, obviously it might be a issue of previous release 12.2.1.1.0, thanks Christian again!

Hi Christian - I have already did that as per your suggestion. Thanks a lot and good luck for us.

And the is server on a linux OS, while we had tried both ways to upload directly in Linux with .sh and upload in Windows through cmd. Neither works though...

Thanks Christian for your prompt reply, it is actually a slightly older version 12.2.1.1.0, but you are right, in most of projects even by using this version, it does not have this problem at all...
