How to force python's VM to print a stack trace?

Question

I'm dealing with a python-written server that locks up, and stops working, including logging. I wonder if there's a python equivalent to java's "kill -3" signal that at least prints the current stacktrace.

Answer 1

You can find a (Unix-only) solution in this question.

Answer 2

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