We are experiencing the same issue using selenium/node-chrome:

unknown error: session deleted because of page crash
I’m using selenium.
Normally it’s working fine but some times it shows the below error :
Message: unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed
(Session info: headless chrome=78.0.3904.70)
(Driver info: chromedriver=2.42.591071 (0b695ff80972cc1a65a5cd643186d2ae582cd4ac),platform=Linux 5.4.0-1029-aws x86_64)
Here is my code :
from flask import Flask, render_template
from selenium import webdriver
app = Flask(__name__)
app.config["DEBUG"] = True
def getInformation(driver, url):
driver.get(url)
res = BeautifulSoup(driver.page_source, 'html.parser')
info = res.find(class_="category_title pcol2")
return info
@app.route("/", methods=["GET", "POST"])
def init():
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument(
"'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36'")
driver = webdriver.Chrome(options=chrome_options)
url = "https://blog.naver.com"
ret = getInformation(driver, url)
driver.quit()
return render_template("checkresult.html", ret=ret)
What’s the wrong with my code? and How can I avoid the exception?

The error says that Chrome is crashing when it tries to load the page, or perhaps when Selenium is getting information from it — with the full stack trace we’d be able to tell which.
If Chrome is crashing, it might be because it’s running out of memory, if you’ve used up more than ten times your CPU quota, or if you have a very large number of processes running so you’ve hit your process limit. In the first two cases, you’d get an email telling you about it — is that happening?

Я использую InstaPy, который использует Python и Selenium. Я запускаю скрипт на Cron, и время от времени он вылетает. Так что это действительно нерегулярно, иногда хорошо проходит. Я уже публиковал сообщения на GitHub Repo, но не получил там ответа, поэтому я спрашиваю здесь, есть ли у кого-то идеи, почему.
Это сервер Ubuntu с цифровым океаном, и я использую его в безголовом режиме. Версия драйвера видна в журнале. вот сообщения об ошибках:

Есть идеи, в чем может быть причина и как ее решить?
Спасибо за вклад. И ребята из http://treestones.ch/ выручили.
I’m using InstaPy which use Python and Selenium. I start the script per Cron and from time to time it crashes. So it’r really irregular, sometimes it runs well through. I’v posted on GitHub Repo as well already but didn’t get an answer there, so i’m asking here now if someone has an idea why.
It’s a digital ocean ubuntu server and i’m using it on headless mode. The driver version are visible on the log. here are error messages:

Any idea what the reason could be and how to solve it?
