• gevent version: 21.12.0, installed via pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

Description:

Hi,

I updated my system from Ubuntu 21.10 to 22.04 (and therefore from Python 3.9 to 3.10) and now our uwsgi application throws the following traceback very often:

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "src/gevent/greenlet.py", line 906, in gevent._gevent_cgreenlet.Greenlet.run
SystemError: <built-in function uwsgi_gevent_request> returned a result with an exception set

AttributeError: 'gevent.libev.corecext.io' object has no attribute 'active'

The above exception was the direct cause of the following exception:

I am not really sure if this is a gevent problem, but hopefully someone can give me hint where to look at.

If any information is missing to help, please let me know.

Best regards, Thomas

After an update to Ubuntu 22.10 the problem is gone.

I have the same issue. I don't want update to 22.10 because it's not LTS version. May be someone can help me to solve this problem or give me some hint?

Best regards.
