Traceback (PusherBadStatus: 599) under heavy load in Tornado library

[michaelperret]

Any ideas as to what may be the root cause here? We aren't seeing any other error logs or issues and this traceback isn't super informative

Exception in callback <function process_response_future at 0x7fd1092058c0> for <tornado.concurrent.Future object at 0x7fd1094c4410>

This means you received an HTTP error code https://httpstatuses.com/599. Are your requests going through a forward proxy by any chance?

For the record, we believe this is due to an underlying issue in the tornado library: tornadoweb/tornado#1753
