[Gluster-devel] Spurious disconnect in 3.4.0alpha

The spurious disconnect I encountered in 3.4 branch still happen in
3.4.0alpha, but glusterfs recovers much better now. However, when
running huge tar -xzf I still hit operation failures, after which
everything is restored to normal state.

Here is the client log, in which the issue is hit at 18:06:36

The relevant part is below. I understand glusterfs is able to restore
its connections and everything works fine, except when it happens on all
volumes simultaneously.
