SOAP request error - possibly a protocol issue (Emergency)

Hi All,

         I have a script to collect all vcenter entity info. It works upto 31/Jan/2015 without any issue . From Feb 1st it didn't collect any datas. We are using "Vim::find_entity_views" for all script . Now we executed the script it returns the output (Mentioned below). Someone helps me to fix this issue.

Error Message :-
