I just got the following test_multiprocessing error (cannot reproduce,

test test_multiprocessing failed -- Traceback (most recent call last):
"/home/antoine/cpython/seek-6629/Lib/test/", line
232, in test_active_children
    self.assertTrue(p in self.active_children())
AssertionError: False is not True

ugh. that's not useful. Dunno how I'm going to track down seemingly random 
and unreproducible issues.

I know, I was posting it for completeness, and it case someone else
witnesses it.

what can we do with this issue? It doesn't seem it happened again after Antoine's report (or at least no-one had followed it up) and it doesn't happen nowdays (f.e. I exec'd test_multiprocessing in a loop for some time, and no error comes).

What do you think about closing it as "sorry, unable to replicate it" and so mark it a glitch somehow?

I've seen that one as well, but very rarely.

well, at least we have a confirmation it's still there :)

any idea how we can try to debug it?

2.5 years later I don't think it's much use keeping this open.
