I'm currently faced with an issue on a server built using Python that freezes unexpectedly, causing the logging to also cease. I am curious if there is a command similar to Java's "kill -3" signal in Python that could print out the current stacktrace for debugging purposes.
To enable better error handling, you can utilize the faulthandler module. You can find more information about it here.
The following code snippet demonstrates how to import and register faulthandler:
import faulthandler
faulthandler.register(signal.SIGUSR1)
By using this module, you are able to handle errors at a lower level in Python's interpreter loop, making it effective even during hang situations caused by other issues.

import signal, traceback
def exit_signal_handler(signum,frame):
traceback.print_stack()
signal.signal(signal.SIGQUIT,exit_signal_handler)
