Etcd 2.2 failed to read raft message (unexpected EOF)

I am running etcd 2.2 on CoreOS 815.0.0.
After discovering all the etcd nodes in the cluster, I get a few error messages about broken pipes and also attempts to upgrade from 2.1:

@F21 From the log, there is some temporal network issues. But I cannot rule out that it is not an etcd issues.
Can you try to reproduce it?

@F21 Upgrading from 2.1 is normal. The etcd member starts with its minimum version until the cluster coverages on a version.

I seem to be able to reproduce it successfully using my vagrant cluster. Vagrant is 1.7.4, Virtualbox is 5.0.6 and my host os is Windows 8.1 64-bit.

@F21 Can you also give me all the logs? Actually I failed to not see anything strange from your pervious log rather than a temp network issue, which is recovered soon.
