Comment 9 for bug 1332440

I can also confirm this running docker with the library/ubuntu:14.04 image on a virtualbox host running ubuntu 14.04

running apt-get update times out or takes an extremely long time.

Host Virtualbox:

$ ulimit -n
1024

docker container:

root@1518e024f53a:/# time apt-get update
