Workaround is because I couldn't find a correct way in ib to reconnect cleanly (with queue kept) when destination is unreachable. When connection is broken, all internal queue contents are being destroyed and reconnects automatically. An "external" send queue is kept until the connection is up again for a dest node. (This used to be ctdb commit 49cac6eafb9d9c80ef1c7f0388aa7786c8be6f24)
