    Dear Managers,

    System Configuration:
      HW: 2 AlphaServer GS80 systems; 4 CPUs each; 4GB Memory each;
      Storage: EMA12000 Disk Array connecting via Fibre Channel
      OS: Tru64 UNIX Version 5.1A; TruCluster Server Version 5.1A; Memory
    Channel Cluster Interconnect

    Problem:
    Suddenly all nodes in the cluster give approximately a 50-second delay
    before offering the "login:" prompt whenever a user does a telnet to
    that node. From any node in the network, whenever the user does a
    telnet <cluster-member IP Address or Cluster-Alias IP Address> you get
    that delay. Even if the telnet client is one of the nodes whose IP
    address to hostname mapping is in the DNS or the /etc/hosts file of the
    cluster. Even when the telnet client is one of the cluster member
    nodes, you still get the delay. Even when you do a telnet localhost on
    one of the cluster members you get the delay.

    I have never before seen this peculiar combination of circumstances and
    I was wondering if any of you can give me some kind of insight into this
    problem. Normally I would check the DNS setup and the resolv.conf and
    the svc.conf files, restart network services and all would be well, but
    this time I just don't seem to be able to get it right.

    I had posted a submission about this **very** early Thursday morning,
    but I got no replies. Maybe I was too incoherent from lack of sleep
    then, so I am posting again.

    Yours sincerely,
    Robert Honore.
