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.
