In a normal BSD kernel, repeated kernel messages (such as 'disk out of
space') are not printed verbatim; instead, just a count of repeated
identical messages is printed for each set.

In dynix, however, kernel messages contain the CPU number; since a
repeated error condition is usually encountered by different processes
running on different CPU's, this causes messages not to be identical, so
each one is printed separately and also stored in /usr/adm/messages.

If you hate to wade through hundreds of identical messages, you can
remove redundant messages by piping the output of /etc/dmesg through
'uniq' - in /usr/lib/crontab, replace the line that runs it by:

0,10,20,30,40,50 * * * * /etc/dmesg - | uniq -c +2  >>/usr/adm/messages

This will have the effect of ignoring the CPU number, and preceding each
line by the number of times it was repeated.  If you really have to see
the CPU numbers, /etc/dmesg can still print the original messages as
stored in the kernel's buffer, and of course the printing on the console
is still unchanged.
