BentoML

Can you tell us more about how to reproduce this bug?

did you have another bentoml server running?

Initially we didn’t have this issue when running on a centos7 server or mac server etc., but recently we switched to an OCI server and started having this issue. We are also running this within a docker image (ubuntu 18.04), base image is `11.6.0-cudnn8-runtime-ubuntu18.04`

<@U01S7CRK58B> did you resolve this issue?

Further testing and comparison showed it’s only happening with `--production` and it’s working fine without this flag.

For a bit more information.

It might be a bit strict to setup same environment and reproduce the bug. There are very little information about this `circus` error on the web.
