I've heard this one before. I don't remember the exact details, but I
think I can guess:

Obviously, it barfs when trying to match group ids to group names, and
what goes wrong involves tcp/ip.
That should be a problem with yp (aka nis).
a. You want to use yp. Make sure that it's setup right, something
obviously isn't. I'm not an yp expert, so I can't tell exactly what.
b. You don't want to use yp, maybe don't even know what it is. It seems
it's enabled, though. I _think_ you'll find a special entry in /etc/groups
indicating to getgrid() that it should do a yp lookup, and removing that
entry will stop your problem. (Similar entries can exist for /etc/passwd.)
Something looking weird like "+:*::" or similar.
