logrotate ignoring 'size' spec ... why?

Code:

---

hi,

i've built and installed LOGROTATE v3.7.4-7.

my lograte.conf includes:

        ====================================
        compresscmd /usr/bin/gzip
        uncompresscmd /usr/bin/gunzip
       
        /var/log/test.log {
                size 1M
                daily
                maxage 30
                rotate 30

                create 640 devuser devgrp
                dateext

                missingok
                notifempty
                sharedscripts

                postrotate
                        kill -HUP `cat /var/process/exim/exim.pid 2>/dev/null` 2> /dev/null || true
                endscript
       
                nomail
                nocompress
        }
        ====================================

currently, test.log is > 3M in size:

        % ls -al /var/log/test.log
                -rw-r----- 1 devuser devgrp 22782552 Oct 16 10:20 test.log

my GOAL, with the above conf, is to exec logrotate hourly, via a cronjob
and have it rotate test.log 'only' once daily, UNLESS the log files has
exceeded 3M, then rotate immediately ...

but, when i exec logrotate, i get:

        "empty log files are not rotated, only log files >= 3145728 bytes
        are rotated, old logs are removed.
       
        considering log /var/log/test.log.
       
        log does not need rotating"

and, test.log is NOT rotated.

what am i config'ing wrong here?

thanks,

richard
