"do_ypcall" is a NIS error message.  (Previous NIS was called "yellow
pages"; the "yp" in do_ypcall is a reference to that).

Maybe you have "hosts: files nis" in /etc/nsswitch.conf or something
else that's causing the OS to want to talk to NIS.

You _DO_ have a problem with your NIS setup somewhere.
