Hi ,

   My appliction is sending some data by using a csv file in bulk and some times during making the connection with salses force my code is as below to make connection:
      partnerConfig=new ConnectorConfig();
      partnerConfig.setUsername(strUserName);
      partnerConfig.setPassword(strPassword);
      partnerConfig.setAuthEndpoint(strAPIURL);
      partnerConnection=new PartnerConnection(partnerConfig);

So when it actually try to make the connection using the last statment of the code snipet it is giving the following exception and this exception occures randomly. Please help me out to know the reason for this .
