...which means this is a bug in engine, not docker-py; server should definitely not segfault when client sends a request
Sorry, something went wrong.
Try updating the engine to 1.10.3?
moby/moby#20638
Ah, my bad, 1.10.3 isn't out yet. However there's a release candidate if you want to test it. https://github.com/docker/docker/releases/tag/v1.10.3-rc1
@xidianwlc seems that you've hit this: moby/moby#20647
