1664.0. "Are there any know FDDI restart problems ?" by CSC32::COLTER () Fri Apr 28 1995 19:08

    My customer has a VAX7640 running V6.1 of OPENVMS  and it a standard
    ethernet as well as  an FDDI.  During the evening (23:00) the customers
    network experienced an FDDI problem that eventually caused the system
    to lock up at 09:00 the following morning.  From the log is appears the
    the last time a restart was attempted was at 7:05 AM.

    The FDDI fiber problem was repaired at 8:00 in the morning, and the
    system hung up around 09:00.  Is there a reason that the FDDI failed to
    restart after the network was repaired?  Does DECNET have a failure
    threshold that will prevent it from trying to restart the FDDI?
