I dont have such problems.  Patch or upgrade to 6.5.13.

IRIX 6.5's nsd is the name service daemon.  It does the lookups be they
via DNS, NIS or whatever.

I never said I use NIS for hostname resolution (and I dont) but I still
need NIS to work for user and group lookups.

You misunderstand the purpose of IRIX nsd and Solaris nscd, they are
not solely for NIS.  They are for caching results of all types of
naming service lookups be it hosts, passwd, services and by all type
of methods e.g. DNS, NIS, NIS+ whatever.

If you look at your IRIX 6.5.X NIS client, you'll see that it doesn't
run a process called ypbind.  The functionality of ypbind has been
incorporated into nsd.  From the nis(7p) manual page:

     The daemon nsd(1M) uses this library to replace the ypbind daemon from
     previous IRIX releases.  Similarly, nsd uses the nisserv(7P) library to
     replace the ypserv daemon from previous releases.

None of that solves the user and group use of NIS problem.

A system-wide cache for hostname resolution via DNS only.
