I don't know the answer but I've seen simular behavior on other platforms (NT for example) Oracle tries connections in different protocalls depending on the SQL-Net protocalls installed. This is a wild guess... It may be tying a tcp/ip connection prior to connecting with bequeath(internal). That may trigger a dns lookup. If I get a long pause when trying to connect it is usually a bad address in the tnsnames.ora file.
