@philips asked me to file an issue; this is running etcd from b4e4bf4

These three machines are VMs on the same host; their interfaces are on the same bridge.

Is this a similar one as #801? Though the error message is a little different, but they indicate the same meaning.
I wonder whether it is possible that this is caused by VM-related stuffs. When I test it in process, or in vagrant, etcds work rather well.

I assume you mean Vagrant building VirtualBox images? I didn't use Vagrant, but I did use VirtualBox.

@jefferai Are you still having this issue?

Unsure. We stopped using etcd (and all software based on etcd) because of #815 . We will evaluate it again at some point when things have a chance to stabilize.
