I'm very sorry for the availability issues. All of my usual tricks for increasing the fd limit didn't work; then I realized this is because of two things: 1. I'm running inside a docker container 2. I'm using ubuntu instead of debian, and upstart conveniently ignores all the usual fd limits places like /etc/security/limits.conf. TL;DR, be careful when experimenting with new fancy technology you don't understand. I hope it's resolved now ;-)
