I think it's two sides of the same problem. SMUX doesn't seem to be
working and because of that I get the messages. If I shutdown OM the
"problem" goes away.

Must admit my ignorance doesn't allow me to see what parameters are
needed for SMUX to work?  I wrote the option file just as you specified
and "ps axf" shows it's been read after a restart; but I'm still getting
the message.

This is a "pure" RHES4 install; not CentOS. Not an upgrade either.
