So the issue is "reopen-logs. Looking at the script
/etc/logrotate.d/php5-fpm

We see:

/var/log/php5-fpm.log {
        rotate 12
        weekly
        missingok
        notifempty
        compress
        delaycompress
        postrotate
                invoke-rc.d php5-fpm reopen-logs > /dev/null
        endscript
}

I suggest the fix is to change 'reopen-logs' to 'restart'. It suppressed warning emails on my system.
Can anyone concur, OR suggest a different workaround?
