Ran into the ARP scale issues when trying to put 1000 containers on a system for scale testing over year ago. strace helped figure out where the issues was and what settings to change. I guess I should have sent an email to the mailing list. At that time if you searched for scaling to 1000 docker contains was a failed search, as it was "hey here is how I scaled to 1000 containers over X numbers of nodes". No one was crazy enough to try to get 1000 on a single machine.
