    I notice now, after the above, the following sort of errors in messages:
    > Apr 24 07:57:56 omnis mDNSResponder: [ID 702911 daemon.error] mDNS_Register_internal: ERROR!! Tried to register AuthRecord 080E9F54 omnis.local. (Addr) that's already in the list

    > Apr 24 07:57:56 omnis mDNSResponder: [ID 702911 daemon.error]  10: ERROR: could not set control socket to non-blocking mode errno 9 (Bad file number)

    the last message is probably the most relevant...
