Steve, We’ll look into your case in more details first thing in the morning (CET time) tomorrow and we’ll fix it, if it’s broken on our side. When it comes to binding on a client side, I can quote Richard Stevens from book “UNIX Network Programming: The Sockets Networking API” that says: “Normally, a TCP client does not bind an IP address to its socket. The kernel chooses the source IP address when the socket is connected, based on the outgoing interface that is used, which in turn is based on the route required to reach the server” From the above you should be fine without binding, but of course - as I mentioned earlier - we’ll check CentOS 7 here and we’ll keep you posted.

Some of the workstations have multiple IP addresses, including those workstations that also double as a MooseFS master server.
