[Erik van Zijst]

Do you have more info on this? Does this happen with Sentry logging only?

I use gunicorn with worker_class = 'gevent'

[Jacob Wegner]

I'm seeing this as well running gunicorn with eventlet on Gondor.io.

[John Watson]

I see this with the gevent worker class, but not with sync. FWIW, while the documentation does say that Dogslow is intended for synchronous workers, it doesn't claim that it won't work with gevent.
