如何处理 httplib.BadStatusLine: ''

Question

我正在使用 Python、BeautifulSoup 和 Selenium 抓取一些网络数据。我也在使用 PyVirtualDisplay，所以我不需要显示器。

它可以在我的笔记本电脑上完美运行，但是当我从服务器运行时，我收到以下错误：

httplib.BadStatusLine: ''

我在第二次抓取页面时得到了这个。它现在一直在这样做。有什么问题？

编辑

添加代码：

import requests, bs4
import csv
import re
import datetime
import time
import os 

from contextlib import closing
from selenium import webdriver
from selenium.webdriver import Firefox # pip install selenium
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
from pyvirtualdisplay import Display

display = Display(visible=0, size=(1500, 1200))
display.start()

url_base = "https://www.seek.com.au/jobs?page="

# open web browser and login
binary = FirefoxBinary('/home/firefox/firefox/firefox')
driver = webdriver.Firefox(firefox_binary=binary)

overlap = False
page = 0

while not overlap:
    page += 1
    driver.get(url_base+str(page))

    ...

这是回溯：

我在一个非常小的服务器（512MB，20GB SSD）上运行它。我已经增加了它，它运行良好。如果有人可以向我解释这个问题，我很乐意理解。
