Please don't ever send 9 megabytes of screenshots and sample files to a mailing list (actually, I was a bit surprised that your images were relatively small compared to the bulk of your log files, although it would still have been a better use of bandwidth to just paste the text from your window rather than capturing screenshots). You caused a lot of unnecessary load on the mail server as it multiplied your message out to every list recipient. Ideally, you should have minimized your problem down to much smaller files - although the nature of the reported problem in diff'ing large files may have indeed required the full log files to reproduce (where trimming things would have made the problem disappear); but even then, hosting your files externally and merely posting a URL in the mail is more considerate when you would otherwise be sending more than 100k to the list. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
