Parent poll failed

Description

What steps will reproduce the problem?

Just freshly installed 64 bit Anaconda 5.3.1 on Windows 7 64 bit and I got this error on my first run of Spyder (Python 3.7):

Python 3.7.0 (default, Jun 28 2018, 08:04:48) [MSC v.1912 64 bit (AMD64)] Type “copyright”, “credits” or “licence” for more information.

I walked through my code and dud unit tests and checked he memory usage in Windows 10 Task Manager. Couldn’t find anything out of the ordinary.

Then I upgraded my Spyder to version 3.3.2. and have been running the same script for over 24 hours continuously. The problem has not occurred.

Looks like it has been fixed (or worked around) in Spyder version 3.3.2.

Thanks and Best Wishes Suresh

I don’t think this is a duplicate because that warning can’t cause a kernel failure. @sureshd2014 https://github.com/sureshd2014’s problem is most probably caused by an error in his/her code.
