    grep "currently marked as unusable" $ADMSG > $TEMP
    grep "No more IP addresses on 192.168.2.0 network" $ADMSG >> $TEMP
    if [ -s $TEMP ]
    then
      diff $TEMP $TEMP.last > /dev/null 2> /dev/null
      if [ $? != "0" ]
      then
        cat $TEMP | mail -s "Log Warnings" yourself@your.dom
        # or use your pntadm if that was your notification
      fi
    fi

    or similar should do the trick.

    You will always have $TEMP and $TEMP.last (if you delete, you will get a
    message about all the messages in your log again and the $TEMP's will be
    recreated.)

    The diff verifies that files differed from last check or were
    nonexistant before a notification is sent out.
