[Gluster-devel] Errors

[Nathan Allen Stratton]

Files go red and contain no data (see below), also still having client
lock ups when a server is down. I don't see any errors in server logs
(debug is on), but things just lock when server is down. When server is
up, but glusterd is down clients work correctly.
