LinuxQuestions.org - python script hang over the screen method in cloud

I have an issue with running python scripts on linode cloud server. I create a scrapping script to scrape data by check in and check out so that i run the script using screen method. It run over one day very smoothly but today it hang. No response. When i call getRequest() method then i print the proxy number and send request with proxy and timeout=10.

Code:

def getRequest(self,url):

                self.proxieName = random.choice(self.proxyDict.keys())

                print getYellow("Proxy: ")+getCyan(self.proxieName)

                self.proxie = self.proxyDict[self.proxieName]

                try:

                        self.getRqst=requests.get(url,headers=self.nrmlHeaders,proxies=self.proxie, timeout=10)

                except Exception, e:

                        print e

                        time.sleep(10)

                        return self.getRequest(url)

                else:

                        if self.getRqst.status_code==200:

                                self.rqstErr = 0

                                return self.getRqst

                        else:

                                self.rqstErr+=1

                                print getYellow("Hi Dear, Don't worry. May be Server down. Exception in Url: ")+url

                                print getRed("Error!!! ")+getBlue("I get Status Code: ")+str(self.getRqst.status_code)

                                print getGreen("I am sleeping now for 10 second")

                                time.sleep(10)

                                return self.getRequest(url)

Here is the image snapshot link https://www.dropbox.com/s/yh2bs7z1mx...error.png?dl=0

after getting the content i parse them and save information into a CSV file and send another request.

And i see also that after 01:40 of 6th July the csv file alos not updated. So it's hanging.
