[New-bugs-announce] [issue35418] python hung or stuck somtimes randomly on windows server 2008R2

[Cao Hongfu]

New submission from Cao Hongfu <cloudnerv at gmail.com>:

Recently, python frequently(but randomly) hung or stuck at initialization(when I click the python.exe or use python cmd prompt) on my server(running windows server 2008R2), But everything is fine on my windows 7 PC). I tried reinstall python, but not working(also tried 3.6).

I tried process-explorer and found that the normal python process allocated about 12MB memory but the stuck one only allocated 8MB memory.

here is the stack information for stuck python process(having 3 threads):
