Hi,
Wow. Never seen that one before. I wonder if it's a threading issue / race
condition.
I looks like there was an error, and then it ran into this error when
trying to send an email about the original error.
What gunicorn worker type are you using?
You could try asking on the gunicorn list too.
You could try removing/commenting out the LOGGING config as that's mostly
the defaults anyway.
