It's hard to say. Unfortunately, we're currently low on quorumd resources, so to speak. So far, those who managed to configure it reported that it works, but that there were problems reconnecting. Search this list's archives. Alternatively, you may try the pingd to manage resources in case of connectivity problems. > Any help is highly appreciated! Sorry that I can't help more here.
