Frames not available in non-suspended state

I am trying to debug a pytest script that hangs.  There are threads that use paramiko to execute remote commands.  
The hang involves those threads failing to sense that the remote  command has completed.

If I run with the debugger (running on a remote server),  I can pause it.

The problem is that the threads I care about only give me "frames not available in non-suspended state."

Any ideas how to get past this?

Hi Adam, could you please switch the suspend policy for a breakpoint to All instead of Thread in Run | View Breakpoints?

Has it helped?

Hi, I have the same problem.

I have changed the breakpoint default (and it's current state) to suspend 'All', but the problem remains.

My code is the following:

from threading import Thread, Event
from time import sleep
import os
import multiprocessing
def foo(process_name, event=None):
    if event:
        print(f'{process_name} waiting')
        event.wait()
    print(process_name, os.getpid(), 'finish')


if __name__ == '__main__':
    e1 = multiprocessing.Event()
    e2 = multiprocessing.Event()

    t1 = Thread(target=foo, args=('t1', e1), name='t1')
    t2 = multiprocessing.Process(target=foo, args=('t2', e2,), name='t2')

    t1.start()
    t2.start()

    while True:
        sleep(0.5)

So when i run on debug mode and am waiting on the sleep(0.5), i get that i can't reach the running thread t1.

Using python 3.7.5, pycharm 2020.1 Pro, win10

Same issue here. I get a mutex lock somewhere, but when I pause it I just get a thread that "works" and is fine but I have no idea which other thread is broken... setting breakpints/enabling all threads is not working as I dont know where it fails. This is useless. Why is there no global checkbox that tells it to monitor all threads?!
