So can anyone at Sun field this?  Is this dynamic reconfiguration of
the console message device?  If so, I "presume" I can expect the
problem anytime the system gets particularly busy.

Atleast its better than not getting the messages anywhere at all (although
they still end up in /usr/adm/messages).

     These are my opinions, and now you have your perceptions of them. */
