Exception KeyError: KeyError(4414541008,) in <module 'threading' about flask-script

Hmm, not sure on this one. I have a similar setup (OSX 10.8, Python 2.7.3 installed via Brew) and have not had any issues like this.

Still experiencing this issue?

Kind of. I understand that it's probably my local problem, so we can close it.

A couple Google searches returned that might be of some help:

It is indeed related to monkey-patching the threading module. In fact, I can easily trigger the exception by importing the threading module before monkey-patching threads. The following 2 lines are enough

import threading
import gevent.monkey; gevent.monkey.patch_thread()

When executed it spits the message about ignored KeyError:

(env)czajnik@autosan:~$ python test.py 
Exception KeyError: KeyError(139924387112272,) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

If you swap the import lines, the problem is gone.

Error is triggered when the python file is modified while running the server.

bottlepy/bottle#362

Problem went away when upgrading to mod_wsgi 3.3

Thank you! I will try to fix it later today :)

You guys discussed the exact problem that I was having. Thanks a bunch.

Same 'error'. I get it out after removing the monkey patching code, turns out no error.
What I did wrong is I forgot to add manager.run(), sigh!
