UPDATE:
The problem exist only, if one of the file size of all the files are larger than 4 MB. Under 4 MB the files are gone the CS without any error. If one of them is larger than 4 MB the error appear and the documentum don't arrive into the CS.
The following parameter have already set in the ini file:
MaxTransferBlockSize=150000, in IIS as well.
What else could be block the traffic?
