I've seen this as well, I got it from upgradeing from
something->netbsd-5-RC1->netbsd-5-RC2.

I suspected something to do with login.conf or other per user
limits stuff. When it wasn't working i had > 80 root owned processes, but
that wasn't near the 16/128 etc proc limits. It did allow root logins again
after many root processes had been killed off but i can't remember exact
figures. I didn't have time to look into it further and got hampered a bit
by PR/40314

I'll look again tommorow if i get a chance.
