Re: 20000321: LDM gethostbyaddr log message (fwd)



Celia-

It appears as if there may be a DNS error.
nslookup currently cannot identify 216.7.162.10
and a traceroute indicates 20 hops and some congestion locally about
216.7.162.10

Both the congestion and the inability to define 216.7.162.10
can cause connection problems. The connectivity is good to Phoenix
( I suspect that is where 216.7.162.10 is located) but gets slowed down
after reaching 216.7....

It is believed that the cache for some DNS entries can become corrupt.

We suggest restarting the name server for 216.7.162.10
