Random timeout when loading the loader

mpgo13 commented 7 years ago

We are experiencing issues with Firefox at the moment. Requesting the url "https://www.gstatic.com/charts/loader.js" sometimes results into Firefox being stuck loading forever with "Transferring data from www.gstatic.com..." being in the statusbar.

Can be reproduced with the following python script using selenium and firefox:


from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

desired_cap = {'os': 'Windows', 'os_version': '7', 'browser': 'Firefox' }

driver = webdriver.Remote(
    command_executor='http://<user>:<password>@hub.browserstack.com:80/wd/hub',
    desired_capabilities=desired_cap)

for num in range(0,1000):
    url = "https://www.gstatic.com/charts/loader.js?ver=%d" % num
    print "GET \"%s\"" % url
    driver.get(url)

driver.quit()

The purpose of the script is to reproduce the issue. We are running automated user acceptance tests with selenium, where we are loading the resource as documented in a normal scenario. Since ~12 July, we experiencing this issue and it keeps us from executing our automated tests.

Hi Martin,

I've noticed some occasional extended delays even in Chrome, so I don't think this is browser related. It might be the server is starting to throttle requests if there are too many in a short period of time. At the moment, the cache time-to-live for the loader is set at only 1 minute, so I can quickly update it if need be. But I will reduce that to 1 hour, and maybe that will help.
