Docker download layers sequentially

问题

is there a way to make docker download the layers of an image sequentially instead of in parallel. I require this due to our repository being very strict (or dodgey) on networking issues. I get a lot of the EOF errors like:

time="2016-06-14T13:15:52.936846635Z" level=debug msg="Error contacting registry http://repo.server/v1/: Get http://repo.server/v1/images/b6...be/layer: EOF"
time="2016-06-14T13:15:52.936924310Z" level=error msg="Download failed: Server error: Status 0 while fetching image layer (b6...be)"

This is when running Docker 1.11.2 on windows.

But on a Centos7 VM it all works fine with the default 1.9.1.

I noticed one difference was that 1.9.1 does the downloads sequentially. So I tried to install 1.9.1 on windows, but the quick start terminal automatically downloaded and installed the 1.11.2 version of the boot2docker ISO.

So is there some arg, config, or environment variable I can set to make docker download the layers one at a time?

Or am I jumping to the wrong conclusion assuming the concurrent downloads are causing my network errors?

Thanks

It seems that there was recently added a max-concurrent-downloads option to the configuration of the docker daemon. Here is the link to the docs although I did not have a chance to test it yet myself.
