solution:
Has not been a problem before this webservice, this is the first reported this wrong. Internet to find information and some say that too much data is out of range, so the end webservice cs modify the configuration file will turn up the parameters, see the problem still exists. In addition, some say that uploaded data contains special characters. I try to debug locally and found the existence of "\ 0" such special characters. Later find the data source will dispose of this particular character and then upload everything is normal.
