Multiple chrome processes after chromedriver.quit()

Question

I am running a Django service that fires up a chromedriver for selenium and scrapes a website for data. The Django service is called by another Java service through HTTP.

Here is the code:

views.py

path_to_chromedriver = '/path/to/chromedriver' 
browser = webdriver.Chrome(executable_path = path_to_chromedriver)
try:
    response = get_data(browser)
except Exception as e:
    print str(e)
finally:
    browser.close()
    browser.quit()

scraper.py

get_data(browser)
    try:
        .
        .
        .
        for i in range(1,6):
            try:
                .
                .
                .
             return "success data"
             except NoSuchElementException:
                 browser.back()
         raise Exception("No results found")
    except Exception as e:
         print str(e)
         raise

The problem is that after the java service has finished making all the calls and the whole process is complete, there are between 25 - 50 chrome processes orphaned in RAM occupying over 1 GB. Is there anything wrong I'm doing here?

Answer 1

That's an old issue. What works for me, although dirty, is to add a sleep before quitting:

time.sleep(5)
browser.quit()
