Thanks for raising this, I have not been able to recreate this locally, but I am seeing this error when I run the tests on TravisCI, which is running on Linux. What platform are you using?

I have published 0.7.9 with a change which I think might fix this issue, the plugin was setting the TCP_NODELAY socket option to get slightly better performance. I have taken that out for now while I investigate why it was failing.

I'm on Ubuntu 15.10.

ok well that makes some sense. The build is now passing on Travis after I moved off the new docker architecture onto the old infrastructure, so I'm hopeful this will have fixed the issue. If not it may be worth trying to run it with root permissions if you are not already.
