Python stops and chrome processes linger
I have already tried the taskkill command on chromedriver.exe and that does not work.
I have increased the RAM on the computer and that does not work.
I am running smaller suites of tests and that is working now.
While running test cases built in the Robot Framework, at some point, the error “Python stopped” appears and I have observed that numerous chrome processes linger per Task Manager even when my test case closes all browser and performs a taskkill command.  As a result, my testing is suspended with aborting the only option.
Background and tech stack:

windows 7/Windows 10
Python 2.7.15/RobotFramework
"scoped_dir*" directories fill up the disk space
Chrome v74/chromedriver v74
Chrome setting turned off:
    Continue running background apps when Google Chrome is closed
Command line taskkill does not always work so only option is to end chrome process in Task Manager.

Test Setup      Run | taskkill /f /t /im chrome.exe
Test Teardown   Run | taskkill /f /t /im chrome.exe
Open Browser
......
Close Browser
Expected result:  chrome process stops running after each test case is executed and all C:\Users\<user_name>\AppData\Local\Temp\scoped_dirXXXXX directories are deleted.
Actual result: "Python stopped" is displayed; more often than not, numerous chrome processes linger and scoped_dir* fills up the file system.
