I ran into this problem when SunOS4.1 first came out.  Turns out it's
caused by running 4.0.3 binaries, perhaps off a file server that hasn't
been upgraded yet.  Bring your whole installation up to spec and the
problem should go away.

Obligatory whines:  It's too bad Sun can't make their releases binary
compatible.  It's too bad comp.sys.sun's turnaround is so slow that
it's useless for debugging.
