SUMMARY: SunOS 4.1.3 in.rwhod reports preposterous load averages

Yesterday, I posted this to sun-managers:

I'm surprized. Normally I get a flood of responses to sun-managers queries,
but this time, the response was underwhelming! :-) Maybe I am the only Sun
user (or at least manager) who finds rwhod useful...

Since my last message, I found a workaround on my own. Suspecting that Sun
just hadn't bothered to recompile in.rwhod for the new release, I hunted
down a copy of the BSD rwhod source (it can be found on,
and zillions of other sites too). It compiled without any problems, and
when I installed and ran it, I found it worked just fine.

Anyway, thanks to David Comay <dsc@seismo.CSS.GOV>, who was the only one to
respond to my query.

And a big fat raspberry to Sun for being sloppy on this one! ;-)
