Are you sure it's the NSCD caching? I had a similar problem recently,
and it was the DNS or ARP cache storing the wrong information for a
server, or something like that.

Check your hosts file, nsswitch.conf, dns records (using host or dig),
and ARP tables. The problem may not be your name service cache.
